    At 1:37, you said "...there is no attraction, nor repulsion...". Wrong. There is attraction or repulsion, depending whether magnet goes toward copper clad or away. Copper is good conductor and magnet generates eddy current, which in turn produce exactly 'mirrored' magnetic field when magnet approaches the surface of the copper. When magnet going away from the copper, you can feel resistance because then magnetic field 'flip'. Still somewhat 'mirrored', but as a 'negative', or in reverse. When magnet going toward copper, north produces eddy current that produces north pole in copper. When you pull magnet from the surface, north pole produces south pole - which attract or as you said - make a feeling of the resistance. When stationary, no eddy current.

      Milan Karakas, Thank you so much for your informative comment. Eddy currents are spectacular. As a boatman, I have used counter-revolving currents to move my boat upstream right alongside the main current flowing in the opposite direction. This is done by employing the counter revolutionary vortexes that run along the edge of the main flow. These forces are often ignored in modern technology. Blessing to you.

      LichtTempler, Along the edge of a fast moving stream of water there are a series of counter-rotating whirlpools of water. These little vortexes as they revolve, form a pulling force opposite to the main flow of the river. The phenomenon happens when the side of the stern of the boat is kept against the edge of the main stream. It will propel the canoe, for example, in the opposite direction of the main flow.

Granit has allot of magnetic properties given it's make up... You just need to vibrate at the correct freq. and it will become workable. Keep in mind we are talking about vibrating only the "B" field of a magnet into the rock!!! You will note at Coral Castle he also had a horizontal stone , similar to Stone Henge... All his magnetic generators were in the repel mode to maximize the "B" field.. SIMILAR TO THOSE Shown ON THE PYRAMIDS OF EGYPT.. FACT!!, THINK about it THAT'S exactly why they used copper tools!!!! You must use copper tools and any iron would totally dispute the field. Quantum Math is total B.S. E=MC2 is also total BS... E=MD. (Magnetic density). Thanks Vincenzo.. Please use your brain!!

    I was an MRI Field Engineer before I retired and we often had fun with the Lenz effect. When MRI's were quite rare, there was always a drawer full of 1" steel washers on bits of string, so that visitors could 'see' the strength of the magnet. We soon got fed up with having to partially dismantle the brutes to get these out when, inevitably, some muppet dropped their washer and it vanished into the bore. We found a spectacular way of demonstrating the strength of the field, safely, by use of aluminium plates, about a foot long, eight inches wide and as thick as we could find - usually about 4mm. (Sorry to mix standards, but that is perfectly logical to me!)
    When the user had a bunch of students or sometimes newbie doctors and we were on the premises, they would always ask us to "...do the trick..." Having first demonstrated that aluminium is not magnetic in any way, you place the plate upright on its short dimension, on the end of the patient table furthest from the bore of the magnet. Then you ask them what would happen if I let go. They all look round, because it's a trick question, right? It''l fall over.
    Of course, as soon as you let go, it falls over and they all look relieved. Then you move the plate as close as you can to the mouth of the bore (disguising the fact that you can feel the Lenz effect working against you.) The you ask, what will happen now, given that it is non magnetic? They look at each other again, this time not so sure, but 99 times out of a hundred they've never heard of the Lenz effect and 'shorted turns'. When you let go and it barely moves (sometimes you have to give it a bit of a shove to get it moving) they are astonished and mystified in equal measure. It falls very, very slowly, although it does accelerate slightly. It's a great trick and a whole lot more spectacular ( and safer) than the old steel washers!

    As other people have said, this also works with aluminum. I have seen magnetic brakes used on a land speed record car that had aluminum wheels, not meant to slow the car from top speed, but to slow it down once the parachutes have been used. It was very ingenious. They had a ring of neodymium magnets on a hydraulically controlled plate.

      The phenomenon is present for any conductor, but the effect is reduced as the conductor chosen is less and less conductive. A silver plate would work better than a copper plate, which works better than aluminum, which works better than zinc, which is better than titanium, etc.

      made one years ago for a small engine dyno. few design flaws but it did work. up to about 20hp, any more and i couldnt get the heat away.
      some brassy unknown material disc from the scrapyard, bunch of neo magnets recessed into very shallow pockets in a steel plate from the back of a speaker, reaction arm on a set of scales, and a lead screw to adjust the magnet gap. the disc spun, coupled to the crank.
      have to complete the circuit at the back of the magnets. gives a nice focused field out the front where its needed. most people tend to miss that point...
      obviously deep pockets just short each magnet out to itself :D
      the disc gets HOT. real freaking hot. every watt of power the dyno is registering is dissipating as heat. could easily stall a 20hp, with power to spare, but the disc was smoking, starting to glow, despite the water spray... design flaws : )
      and neos fail rapidly at 70C+. lol. ferrite will take 150C or so, and alnico will tolerate redhot, but is a bit pathetic... and expensive...
      i brushed the dust off it lately, revisiting the idea. it promises a certain advantage over any thing else in the application of certain "renewables"...
      get carried away with this idea of "electrons" and forget that they need something to pump them, just like hydraulic fluid in a bottle is basically useless but will give you gangrene at 20,000psi from a leak, or move a large rock in an excavator bucket... and whilst hydraulic fluid happily sits in a bottle, electrons tend to dislike each other and refuse to congregate in large numbers unless beaten with a large stick...
      this is hands down one of the best videos but he did miss the bit with the coil, open circuit, shorted, LED... a decade resistance box would have shown something even more interesting, along with some maths relating to the mass of the magnet and gravity... EFFICIENCY. or, load matching, and how it relates to efficiency. where is the work done, how does it relate to the mass of copper versus the magnet strength, its mass, teh resistance of the copper wire as its wound, blah blah...
      where is the work done in a generator, where is the load, and what are their limitations?

Called a supplier today for liquid helium and the minimum order is 180L...So not sure what exactly I would do with the rest of it, if I could even afford it.

MgB2 would be a great option though.

Once you understand the "B" field of a magnet and how it relates to the entire universe we live in, you will then understand what Tesla was telling everyone "LOOK FOR WHAT YOU CANNOT SEE"" .I believe the pyramids were inter galactic communications and transportation systems. Stone Henge and Gobekli Tepe , power plants. Take a look at Coral Castle Florida on RUclips and you will see a similar pilar. I believe these horizontal pillars were oscillators that would provide excitation for many things from crops in the field to anti gravity FYI: If a UFO fly's to close to you the "B" field that provides the anti gravity ("B")Field). will cancel out your power source !!!!

      Magnets on this planet are just sympathetic magnets of the earth's double torus magnetosphere.
      We live in an electric universe powered by and held in position between the double torus's of galaxy, sun, planets magnetosphere.
      Precious metals are magnetic ISOLATORS of the double torus magnetosphere.
      Earth's magnetosphere is powered by the Sun's magnetosphere which in turn is powered regulated by it's position relative the galaxies Bulge & nucleus.
      The GALACTIC Milankovitch cycles cause our cliamte trends and cataclysms.
      Eccentricity being the 235,000 year rotation of the galactic bulge. Antikythera device was a predictor. We are at year 201,000.
      Obliquity is the climate trends between aphelion and perihelion with the galactic bulge. every 60,000 years we are 34,000 years away from perihelion with the galactic bulge.
      26,000 year Precession of the equinoxes or Magnetic north, eclipsing the nucleus of the galaxies magnetosphere causes an exponential rise in magnetic/gravitational energy for the 1,000 years it takes to eclipse the galactic plane equator.
      We started crossing in 2012 like the Mayans predicted and magnetic north shows. We are at 24 degrees west declination increasing towards the centre of the double torus in 500 years. when it will switch to 24.5 degrees East delineation decreasing for 6,000 years.
      Jesus warned us about these the climate change END TIMES with the book of REVELATION & the cause with the 7 north stars of the PRECESSION of the Alpha Omega equinoxes he held in his hand.
      These are just the birthing pains. Mother Earth's WATER won't break until the 2033 conjunction of Mercury-Venus-Earth causes the MOON to pull the earth's increased magnetosphere & oceans out and around the planet east to west 800 mph at the equator as in the days of Noah.
      We are not Gods. We are not causing the Sun's magnetosphere energy output to increase.
      The PRECESSION of the vernal autumnal equinoxes is.
      Jesus unites us & warned us all.

    Laser levels use this to dampen unwanted vibrations. A copper disk is mounted at the bottom of a pendulum that is free to pivot. A magnet is mounted below the copper disk and causes the laser to self level rapidly and be resistant to small vibrations applied to the mount. In this application the magnet is stationary to avoid magnetic fields including that of the earth from effecting the accuracy of the laser level. Without the magnet, the laser would eventually self level, but would be too sensitive to vibrations to be useful in most construction environments.

    i was just thinking about this video, and i think its possible to polish the surface of steel using magnetic breaking. the traveling fair where i live has a ride that takes you up about 100 feet on a tower and drops you. The way the ride stops is electromagnetic breaks that fit around metal fins. from what i remember, there were 4 metal fins that were at least a foot long and probably 8 inches wide. likely, they were bigger as they were far up on the ride. the part of the ride with the seats that falls rides on a square piece of scaffold with wheels to keep it aligned, and it has 8 electro magnets, one for each side of the fin. the fins are attached to the outter framework of the ride, so force applied to the fins sits on cement pads placed on the ground. the failsafe is a massive pile of recycled tires under the seats. if the magnetic breaking fails, you literally just land on a huge pile of rubber.
    The interesting thing to me is that the fins were POLISHED. They stood out as extremely polished to a perfect mirror finish, and the polished part of the fins was only where the breaks run over them. It has always made me wonder if some kind of surface stripping happens when you are breaking such a massive load over a fairly short distance. also it freaked me out that the ride didn't use permanent magnets and only have a pile of tires as a failsafe.

      Older, pre-electronic coin sorters used magnets to slow down 'slugs', steel fake coins.
      Coins rolled down a short ramp, magnets on either side.
      Eddy-current drag slowed down slugs, regular coins went through at full speed.
      At the end of the ramp was a little jump; fast coins jumped a gap, slow coins fell into the gap.
      They had trouble with Canadian coins, their nickle content made them somewhat magnetic and they jammed the ramp.

      for an organization that has made a big stink about 'fake news articles' they really don't seem to do much about the dearth of straight up useless and stolen content on the front page of every search other than putting big check marks next to legacy outlets that i'm pretty sure nobody trusts anymore

      But I work in broadcast radio, there is no such thing as "free content." You don't pay to watch content on RUclips the same way you don't pay for radio.
      The money has to come from somewhere. If everyone just donated through Patreon, there'd be no RUclips, no radio, no broadcast television. No channels like this. No channels period...since the platform wouldn't exist.
      We all hate ads, but, without someone paying for the platform and the content, we'd have no free content to consume.
      We'd have to....go outside and use or imaginations!
      We couldn't even read books...since books aren't free...and the free ones would be sponsored.

    • @MattsAwesomeStuff
      @MattsAwesomeStuff 7 лет назад +10

      Geek Therapy Radio - My problem specifically with in-content advertising is just that, it is part of the content. That's fine for disposable vloggy or newsy videos that have no archival purpose, that, frankly, if they were deleted in a week no one would notice or care. But when it's baked in, it's inseparable from the content itself. 10 years from now this video will still be every bit as relevant as it is today, but the ad will likely no longer be relevant, the company probably won't even exist. Maybe in 5 years there will be a new video platform instead of RUclips, but, now it'll have to get edited because there's weird advertising baked into the actual content. Other than historical comedic purposes, like seeing the ads that played on the Beta recording of Starwars Holiday Special, it's weird. In-content advertising works great for the content type that is swamping the content type I do like. Stuff that's low-effort and relevant only because it's new.
      But, like I said, I get it. From what I understand, most of the companies that want you shilling for them don't pay you by view count, they're just paying for your "reach", your amount of subscribers. And the amount you get from a shill video is like, 10x, 20x or more than you get for out-content advertising from Adsense (partially harmed by adblocking, can't block the ads in the actual content). Ads aren't necessary, but, my Patreon slate is full so I can't complain. Without these ads there likely wouldn't be this content and I certainly wouldn't want that.
      Just kinda idly complaining about the way the world is. I don't have a better solution.

STUPID HUMANS!! We went backwards in the Iron age!! the center of a magnet is where we belong after all that's what we are all configured with..FACT!
      Please review the works at "CORAL CASTLE, Florida. (RUclips), He would "VIBRATE" ,, not oscillate the granite at a resonant frequency to the type stone he was working with. Granit has allot of magnetic properties given it's make up... You just need to vibrate at the correct freq. and it will become workable. Keep in mind we are talking about vibrating only the "B" field of a magnet into the rock!!! You will note at Coral Castle he also had a horizontal stone , similar to Stone Henge... All his magnetic generators were in the repel mode to maximize the "B" field.. SIMILAR TO THOSE Shown ON THE PYRAMIDS OF EGYPT.. FACT!!, THINK about it THAT'S exactly why they used copper tools!!!! You must use copper tools and any iron would totally dispute the field. Quantum Math is total B.S. E=MC2 is also total BS... E=MD. (Magnetic density). Thanks Vincenzo.. Please use your brain!! If your professor gives you any flack, have him explain the speed of magnetism. It's instantaneous.
      That's how they used the pyramids as transportation devices, inter Galaxy type transportation that's exactly why they were 8 sides to create a perfect hologram from earths magnetic field that could be used to connect interglacially

    The plates gets pretty hot, by the end of the operational day. Honestly, I never thought about measuring the temperature. I figure it’s around 130 to 140 degrees Fahrenheit. It takes a couple of hours, for the plates, to cool down completely.

Best you might be able to do, would be to use the heat to warm a few rooms in the winter(even then, those room would have to be close by). But then you’d have to go to the trouble of installing some sort of heat transfer system and a backup system for when those plates aren’t enough or aren’t in use. It’s a lot of money and upkeep for a marginal improvement in efficiency.

    • @CJ-442
      @CJ-442 3 года назад +3

      @@jakemccoy If you’re goal is to reduce heating on those copper plates, then the answer is no. Magnetic breaking works by converting the kinetic energy of the moving magnet into eddy currents within a conductor, which is then converted to heat. Connecting a “load” (like those LEDs) to the plates would create a complete circuit and greatly reduce the eddy currents in the plate, and therefore, its breaking power as well. You saw that in the video when he dropped that magnet through the coil with the light connected. It generated electricity, but the magnet barely slowed down at all. That’s why I suggested using the heat transfer system to heat a room. That heat has to be generated for the breaks to work, so you may as well try to use that heat for something useful.
      If you’re asking if it’s possible to use the coaster’s movement over those plate to generate useable electricity, then the answer is maybe. It’s not impossible to do, but you’d basically have to design a coaster with having that dual breaking/electrical generation purpose in mind. You’d need some sort of system installed to ensure that only a little bit of the electricity was taken from the eddy currents; that way the breaks still work. Also, anything that you’d hook up to this system (LEDs, speakers, etc.) would only work while the coaster was moving over the plates. When it’s anywhere else or completely stopped, electricity stops being generated and the “load” is no longer powered. Again, a lot of work, money, and upkeep for a marginal improvement in efficiency.
      Not hounding on you or saying it’s wrong to try to come up with new ideas. I just deal with electrical systems a lot in my line of work, and these are the things that I have to think about. Introducing changes or new purposes into a system also introduces the possibility for new problems, so you have to take those problems into account. Is it worth having one system that does 2 things if it only works 75% the time? Or is it better to have 2 systems that do 1 thing each and they both function 99.9999% of the time? The answer is that it just depends on what you’re doing. Using waste heat generated by flushing the toilets to warm a maintenance shed in the winter is a lot less important than having breaks that function properly.

    This is great! I'm finally starting to understand how electricity is really made!
    I used to be told it was just steam running a turbine. I could never understand how it gets into our wires. Now I see there is an electromagnetic field that is stimulated by interaction of magnets and electrons

    • @martinkuliza
      @martinkuliza 4 года назад +2

      steam through a turbine hehe oh.. you gotta love it
      ok, firstly it's not MADE, it's GENERATED
      which is why things that make electricity are called GENERATORS
      Secondly .. Electricity is just merely the movement of electrons through a conductor.
      or in other explanations
      a Copper Atom has electrons, and a certain number of electrons occupy each electron shell.
      we are just concerned with the outer shell
      this shell is called the VALENCE SHELL
      and the 1 electron in the outer shell is called the VALENCE ELECTRON
      Copper has 1 Atom in it's valence shell
      and as such it would rather it LOSES an electron (That's how atoms work)
      simply stated, an INSULATOR is an atom that would rather NOT LOSE it's electrons
      a CONDUCTOR is an atom that would prefer to lose an electron or electrons
      MAKE SENSE ?
      so it's not important to understand the magnetic part of it .
      Electrons have an electromagnetic field, REMEMBER THIS
      now. when you line up (for arguments sake) one copper atom next to another and another and so on and they are all a certain distance from each other, but not too far either
      BETWEEN THE ATOMS.... you get a force basically think of it as the South pole ofa magnet trying to come close to the south pole of another magnet
      so.... ELECTRONS ARE NEGATIVELY CHARGED
      and hence Negative repels Negative... right ?
      so.. when an electron gets close to another electron... THEY REPEL
      the FORCE that causes this repulsion is called EMF Electro Motive Force
      now... remember that line of electrons
      now..... IF YOU WERE TO PUSH 1 MORE ELECTRON INTO THE CIRCUIT
      HERE IS WHAT WOULD HAPPEN
      THAT FIRST ELECTRON , VIA EMF, CAUSES THE ELECTRON NEXT TO IT TO JUMP TO THE NEXT COPPER ATOM.
      and that..... CAUSES THE ELECTRON IN THAT SHELL TO JUMP TO THE NEXT ATOM AND SO ON AND SO ON
      AND VOILA....... ELECTRICITY FLOWS
      and where does that first electron come from ?
      well.... A Generator, a Battery, some external power source
      does that help you understand electricity and how it's generated ?

    You could insert the magnets into a wheel that spins with a motor and spin them above or below the copper and check the temperature of the copper as it rises with IR thermometer. This would effectively demonstrate this heating effect of the electricity inside the copper imposed by the magnets.
    There are also magnetic mixers for chemistry that spin magnets below a surface. The copper plate might heat up from one of those also, but to a lesser degree.
    This is theoretical, but demonstrating it would be a nice proof of concept.

Then the ring drops, and when it gets close to the bottom, the phenomenon explained in this video brakes it to a halt.

    I've always thought this would be a great way to land vertical take off and landing machines, like the reusable boosters from Space-X. Not only would they resist change when landing, they would also absorb shock from higher speeds. I think they would allow some sort of loose "grappling" effect in the case of the moving landing base(OCISLY for example) and would stabilize it before actually touching the surface.

    • @crackedemerald4930
      @crackedemerald4930 7 лет назад +33

      They would need ENORMOUS electromagnets and batteries (maybe not too big, since it would be an one time thing and it would be just a pulse. In that case, just a big ol' capacitor would work)
      And those things would add weight to a rocket which is an analogy to something you generally don't want to do
      The base would also be a little heavy since it would need a continuous or a few big plates, why is weight a problem? Don't those things land in barges?
      The magnetic break thing might not be a so good of an idea simply because of the fact that it would just be a hard break coming earlier, instead of hitting the ground, it hits the magnetic field, making it about the same thing as hitting the ground, because the deceleration would be about the same
      There's hope though, if the rocket has the coil on the outside and it has a little tube or something, it would have more time to break

    This is one of the coolest videos I've seen in a long time. I'm fully aware of the back-emf and resistive forces forces generated by the copper through learning how motors and generators operate but never thought of this sort of behavior. Seeing it applied here just shows that we have barely begun to explore the interaction of magnets and copper (or aluminum or another strong conductor).

    • @you_just
      @you_just 3 года назад +1

      on the contrary, this behavior is well-understood by physicists-- the entirety of this video can be summed up with the rather elegant equation
      ∫E͐•dr͐ = -d/dt ∫B͐•dS͐
      the essence of this equation is that nature will combat (the negative sign) a change (denoted by the derivative, d/dt) in magnetic flux (which is basically just how much magnetic field (B͐) is going through an area (dS͐)) with an induced voltage (E͐) through a wire (dr͐).
      what this means is that conductors will resist¹ not the _presence_ of magnetic fields, but a _change_ in magnetic fields. copper doesn't care if magnetic fields are near it, only if you try to _change_ how much magnetic field is near it. this is why we have to move magnets in generators to be able to get electricity. contrast this with electric fields-- the mere presence of an electric field, not it changing, is what drives a current in a wire.
      ¹the way the copper physically resists the magnetic field is with its own induced magnetic field. electrical current always produces a magnetic field, and it just so happens that the induced current in a conductor from an external magnetic field will always be in the opposite direction to the change that created it. so, if you move the north side of a magnet towards a conductive material, the material will temporarily become an electromagnet with its north side facing the approaching north side of the magnet. pretty cool stuff

      this video is possibly the best i have seen on the subject, im just disappointed that he didnt show what happens with different resistances in the circuit rather than short, open, and LED... how a different number of turns for the same mass of copper gives different effects with different load resistances... that the magnet falling from a set height always contains a certain amount of energy.
      how much energy is extracted? can be extracted? whats the limit?
      wheres the work being done, and wheres the energy being dissipated?

In the book cities are able to take flight via control of the electro/magnetic field, the device was called a "Spin Dizzy." Now all atoms have a magnetic field - correct? All atoms are affected by electro/magnetism. I believe the key lies within the vibration and frequency of the atoms in association/resonance with the magntic field.

      Where v is the speed, B is the field strength in teslas, L is the width of the bullet, R is the resistance across the with of the bullet and M is the mass of the bullet.
      (with no air resistance of course)
      Then v(t) = u * e^(--B^2 * L^2/(MR) * t)
      u is the initial speed
      With no air resistance the bullet supposedly never stops moving as observed from the equation, but anyway the field required would be very strong to slow it down quickly enough.

  • @AustinSteingrube
    @AustinSteingrube 6 лет назад +69

    Electrical engineer here: Great video, but a couple quick corrections: At ~1:17, your explanation of the magnetic dampening demos is that "electrons were perfectly happy being being where they were before the magnet tried moving them around, so they resist this movement by generating a temporary magnetic field of there own. There's no attraction or repulsion, just resistance to change." This isn't correct (and this goes beyond semantical nitpicking).
    A changing magnetic field in a coil or a large chunk of metal generates a voltage (referred to as an EMF). The electrons HAPPILY move around as fast as they can; they don't care where they are or were and don't resist anything themselves. When the electrons move, they do (as you mention) create a magnetic field which is opposite to the neodymium magnet you dropped on them. In other words, THERE IS ABSOLUTELY REPULSION.
    The reason the magnets don't just float forever is because electrical resistance in the copper itself turns some of the electrical current into heat. This is the only "resistance" in the system; it is a property of the material, not a property of the electrons themselves.

      So you are exposed as a bullshit-spewing grandstander yet again.
      I do not claim to make such a clear and concise explanation here but there are two forces that could possibly be at play in terms of supporting a floating magnet over a "semi-i finite copper sheet": magnetic and electrostatic. The magnet would have to induce an equal and opposite force in the copper. The problem is that it is a magnet not a battery or other voltage-generating device (like an antenna) so that rules out electric repulsion. The magnet motion must induce an opposing magnetic force which disappears when the magnet stops moving normal to the sheet. But electrons only generate a magnetic force while they are in motion and that force is the cross-product of the charge and the motion-vector. The point is that of the sheet to generate an opposing magnetic force through the generation of electron movement induced by the magnet, some sort of virtual circuit would have to be created in the sheet which is of a configuration to generate such a field. A lot of virtualization and equivocation is required to explain this phenomenon. But sure assume a virtual coil is set up in the copper sheet to provide a closed path for electrons to move to generate the opposing field. The opposing field still relies on the magnet motion. That is really all there is to this. No need to talk about heat etc. Or your having an EE degree. Supposedly.
      Now try it with superconductors for extra credit.

      You talk about how he was too wordy, then wrote 4-5 paragraphs yourself stating the same thing over and over. To quote you: "you are exposed as a bullshit-spewing grandstander", "If you truly understand a physical phenomenon ypu should be able to explain it clearly and succintly"
      He mentioned his degree to give reliability to his statement. In a debate, it is a way of supporting your point. Furthermore, electrical engineers deal with electromagnetism every day (circuit boards and power transmission rely on these principles heavily). Therefore, he is also stating, by saying he is an EE, that he has good practical experience on the topic.
      By the way, he is correct. The eddy currents generated by the moving magnet produce an opposing magnetic field, and hence there is repulsion. There is repulsion between the 2 magnetic fields. The eddy currents face resistance from the copper, which is why the repulsion dies down and the magnet doesn't levitate, since the source of the repulsion (the eddy currents) lose their energy as heat. In a super conductor, with no resistance, the eddy currents remain and the magnet levitates (although, there is more too it).
      And as far as comparing an engineer to a physist, as you said: "Nothing compared to being a properly trained physicist." Engineers directly apply the laws and models made by scientists. In many ways, they have a perspective of physics that pure physicists don't. It is why so much physics has been done by engineers, and many physicists are also engineers. After all, physicists didn't design the computer you are typing on, or the internet you are using. It was engineers. I could go on, but I doubt you are the type of person to look at things neutrally, afterall, your entire comment was filled with unnecessary insults and a complete misunderstanding of the OP's comment.

    Wow! Thank you so much for this really cool experiment! It definitely had me "wowing" during the magnet dropping toward the copper plate. The slow motion dampening was really cool to see in action! I've been curious about electricity my whole life as far as I can remember since being inspired by Mr. Wizard from back in the 1980's on Nickolodeon. This really gave me the child like curiosity that I miss. I would describe it as the modern day tinkerer and makers crowd. Thanks again and keep up the good work!

      E=MC2 is a joke! OK let's get this correct !! #1 The only reason radio waves and AC current travel out in space and down a wire is because of the "CENTER " of a magnetic field. (The "B" field), The North and South poles are the weakest part of a magnet !! Just like Tesla said, you got to look at things you can't see !! At the center of a magnet is anti gravity, (just tap the center on any glass or plastic and it will loose weight), The center can repel water if vibrated at the correct frequency, If you vibrate the "B" field into granite rock it will become soft and you would need copper tools to work on same , you don't want to disrupt the magnetic (B")field ) with other iron. Once you understand the "B" field of a magnet and how it relates to the entire universe we live in, you will then understand what Tesla was telling everyone "LOOK FOR WHAT YOU CANNOT SEE"" .I believe the pyramids were inter galactic communications and transportation systems. Stone Henge and Gobekli Tepe , power plants. Take a look at Coral Castle Florida on RUclips and you will see a similar pilar. I believe these horizontal pillars were oscillators that would provide excitation for many things from crops in the field to anti gravity FYI: If a UFO fly's to close to you the "B" field that provides the anti gravity ("B")Field). will cancel out your power source !!!! E=MC2 is at best just a joke!!!

    until now I never really understood why electricity generation was so inefficient or how you could measure draw from an alternator or generator. I didn't realize that the amount of current the copper generates in response to the magnet actually forces the magnet to slow down. I learned today.

      However, I hope you did notice that when an LED was connected, the magnet did NOT slow down much.

    Really good explanation. I would just add a common misconception that I, myself had when I was younger:
    Electrons DO NOT flow through the whole wire. In fact, they barely move.
    What DOES move at the speed of light is the electrectomagnetic field generated, which is the one thar produces the resistance.
    This is a misconception that even electrical engineers that I've met have. Yet can be explained by Maxwell's equations.

    When Neodymium became available ~1994 another engineer showed me the drip a dime on a magnet trick next to my ear. It made no sound. I bought some surplus magnets mail order from Harry Epstein. The box arrived empty with a hole in the side. The magnets had stuck to a truck and were long gone.
