Signature Edits I’m not sure the there is any way around the copper coils and magnets but the method in which we turn these generator turbines is insane. Our first idea has been one of the best. Use falling water. But then the next 2 are out there. 1.) Let’s dig up Old dinosaurs and plants from millions of years ago, light it on fire and boil a big pot of water to create steam.

Oliver Heaviside is the most underrated scientist ever. In school they teach us about Galvano, Ampere, Tesla and so on, but never Heaviside. Oliver Heaviside was an autodidact (self-taught) mathematician and physicist. He coined all the terms used in AC circuit analysis, he invented vector calculus and his work changed telecommunications. Fun fact: since he wasnt formally educated, he was in conflict with the scientific establishment his whole life
@@stuckonearth4967 It's not just Heavyside. Elon Musk naming his company Tesla may be the only reason we know that name. The masters tried to sweep him under the rug and discredit him too. The crime is not being self taught it's anything that redistributes power or wealth from the masters. This goes back to ancient times and the story of Prometheus who stole fire from the Gods in 500 BC. Zeues crucified him to rock and had an eagle eat out his liver, which would regenerate so Prometheus could be tortured again the next day at infinitum. The moral of the story is when you discover something and don't bring the current powers that be with you unveil it the power you unleash may become so imbalanced that it lashes out against you. So unfortunately advancements will probably have to include big oil and the most polluting companies or they may react so sharply against that new scientist, that he will join Heavyside, Tesla, and Prometheus.
Your videos should be mandatory in school as an introduction to a new subject, they usually make it SO much easier to understand a course. Many teachers know the subject, but they can't teach it. Your videos are usually "reference level" in both cases...
This has to be in the top 5 channels on youtube. Incredible explanations and hysterical commentary. I think I've laughed to tears at least three times watching this channel.
I jumped on this as fast as I could and you already had 230 views and 38 likes. Keep this up dude, you not only matter so much to me as someone that was screwed out of a proper formal education in the sciences, but I pass this stuff to my (at the moment:) 9yo nephew and use it to explain things ostensibly "beyond" his ken. You're making a huge fucking difference, man, keep going, even though it won't be immediately visible. You're not just making my 30yo ass smarter, but I use your material to encourage kids I know. KEEP THIS UP, and I'll be supporting you via patreon in a few weeks (sorry, I'm poor :C)
I think the important thing that people often miss is that when current in drawn from the voltage source (so power), a torque is created so that it impedes the rotation. So we don't only have to make spin the rotor "once" to give it momentum, but apply a constant power at least as much as the drawn electric power.
I don't think anyone misses that. If you could spin a rotor with one push and it ran forever and ever having a perpetual motion machine there would be no issues regarding power or the climate. Perpetual motion machines aren't even really pursued anymore except as RUclips click bait. All the solutions for clean renewable energy have been invented. Will we have the resolve to implement them or will we go down in history as the monsters that set in motion the destruction of all life on Earth. Knowing full well it was happening and how to stop it, but did nothing.
@@anthonypape6862 Your'e in the good side but trust me, almost 99% non tech would imagine that it might be possible to retrieve more energy (and especially because they don't really feel what "torque" is but only speed). I have a vid with exactly this point explained, it has +2M views, and it's not sufficient to convince everyone!
@@ScienceAsylum how is the valence of the conductive metal refilled after electricity flows though it? i realize it they are lost and contributed one to another in a flow of electrons down a wire but somethings has to refill the valence shell electron in the original atoms that was lost. Anyone know??
@@Acuraintegraman1 It doesn't _need_ to be refilled because it's a closed circuit. Imagine a closed pipe system where water never leaves. Do you need to refill it with water?
3:30 It's also worth to mention that when there is something connected drawing current from the generator, it gets harder to spin (I guess you'll cover Lenz's Law in a future video). That's why infinity energy generators don't work. When there's no current flowing, all the force you apply is turn into motion, and since nothing is consuming energy, the coil would continue to rotate indefinitely, if there was no losses due to friction and drag. However when something is connected, creating an electrical circuit, part of the kinectic energy of the coil is turned into electrical energy. Thus if the torque applied is constant, the angular speed of the coil will reduce, or conversely, to make the speed constant, a higher torque is needed.
This a good point and something that might be worth doing a solo video on. I remember we did experiments like this in physics class. Let a pendulum swing through a magnetic field and it swings normally. Replace the head of the pendulum with something conductive like copper and the pendulum swinging stops really quickly, the breaking action is really evident. What's going on is that the magnetic field induces a current within the copper, little electrical loops. Because this takes energy, the energy has to come from the motion of the pendulum. Hence the pendulum stops moving very quickly because those current loops are actually using up a lot of energy. The point of the lesson was the same as yours: perpetual motion energy-making machines don't work. That energy really has to come from somewhere, and there ain't no free lunch.
@urmthrwan Yes, in theory it would be possible if you also eliminate the mechanical losses (friction and drag). It makes sense considering that the power is given by the product of the voltage across a device by the current passing through it: P = V x I. Usually, the power is zero if there's no load, meaning there's no current regardless of the voltage generated. In this setup though, there would be no power dissipated because there would be no voltage drop between the ends of the coil, regardless of the current passing through it, so the power equation becomes zero too. I don't see any practical application of this kind of generator though.
Have to be honest, first time watching one of your videos I felt like they was meant to be just for kids, but now I really enjoy each one of them. They are explained so well, in such details without all that misleadings examples that are used to supposedly help us understand.

Thank you, your video explained it really well, i love how you made it clear that magnetic induction/spinning coils around is the actual source of energy. I was really confused trying to understand how Nuclear Powerplants work
The original source of our energy is the Sun. All we do is convert energy to a more convenient type. We have never made or destroyed energy. It just is, and it's free in the raw state as when Sun bathing. All conversion is costly and has inefficiencies. Sun to electricity by photovoltaic panels, wind to mechanical, to generation, fuel to mechanical to generation.
Just wanted to throw some inconsistent encouragement your way. I'm not a scientist, or use what you teach in any way. I'm a meditation teacher. But as a teacher I recognize that you do more than just entertain us or help students pass tests. You are following a passion, discussing the nature of the universe. And despite the fact that it may not bring you wealth or much utility, it adds something important to the question of what it means to be human.

Question not about electricity but black holes: An old video mentions that there is infinite time dilation at the event horizon; a distant observer would never see a falling clone cross the event horizon. So how to black holes feed or merge, and how can we see evidence of it, if the time dilation for objects falling into a black hole is so severe that it never "happens" for us?
For a distant observer, it doesn't actually matter if stuff crosses the horizon. If it's close, it's still adding to the mass located in that general area.
I have to add to the beginning of this comment, all credit to Nick, he did mention the wire was insulated..... I know this is a really basic point to make, but I've noticed in the past when someone who is attempting their very first coil, they don't realise that the copper wire here is actually insulated and then, don't understand why their coil doesn't work because they've stripped down to a bare copper wire to start their coil. Science Asylums copper wire has a thin clear lacquer coating to prevent the wire from touching itself.
In calculus I always heard about the "Heaviside step function" and I honestly thought it was "heavy-side" like heavy vs light and had something to do with taking the value of 1 rather than 0 at 0 until I quite recently (but not today) learned there was a physicist named "Heaviside" who invented electromagnetism and vector calculus.
Taylor Polynomials is another interesting coincidence where the mathematician's name describes the concept he contributed to mathematics. A Taylor polynomial is tailored to match the function.

Usually it's the magnet that spins, and not the coils. It's easier to extract power from stationary coils. The magnetic field can be created by a spinning coil, but it operates at a lower voltage which can be passed into the rotor by slip rings or a transformer
@@ScienceAsylum so i guess that means that the direction of the magnetic field on that axis doesnt matter for the Lorentz Force? both the conventional current and electron flow in that wire create Lorentz Force in the same direction? (of course it needs to be perpendicular, but already is as seen in video)
Wonderful explanation! This channel is the Oliver Heaviside of RUclips. On a positive note, the improved YT algorithm has actually provided me with something useful.
You make science interesting in a way that would have taught me a LOT more in the science classes I was FORCED to take... and for a LOT less money. Being crazy is part of it... all the BEST people are, you know :))
Voltage is actually the potential for charges like electrons in the electric field. A potential is always the difference of energy of the particle at a point compared to the energy at a reference point diveded by the charge itself. So if you multiply the voltage (or the potential) at a point by a charge you get its energy at this point. Or in other words the higher the voltage, the higher is the energy of charge at that voltage.
By energy i mean the potential energy und note that you dont always divide by the charge. For example there is also a potential for the gravitational field which is the difference of potential energy divided by the mass. So in general the potential of a force field in physics is the potential energy divided by the quantity which causes the force. The cause of the force in the electric field is the charge.
The microphone you talk into converts a metal plate's motion into electricity. A magnet provides the field and a coil collects the current. Vibrations from your voice make the mic's plate vibrate, same in guitar pickups where the strings replace the plate. Scream close to a guitar string, and the amp will actually project your voice.
Nick Lucid, you are the best teacher i ever saw and these videolessons are so exeptionally clear, i wish you where my teacher in my school. A pity i am dutch, but the school where you work shall and will without doubt deliver science students noticable above the average, in number ánd level. You are unique on youtube, thats for sure!
Omg, i am almost tearing.. It was hard for me to get a full understanding of the magnetic induction for 2 months.. And u just simplified everything for me in less than 7 minutes.. Thank you so much ❤️❤️
one crazy question nick ! imagine if we isolate a black hole ....and start "feeding" ELECTRON ONLY. what will happen if we continue to feed..also consider that black hole also SPIN. will it produce magnetic field also?
I believe it should be plausible. However, getting a black hole charged to the extent that it produces a magnetic field great enough to be used from the distances we can reach would require an immense quantity of charged particles to be sent within it. Nonetheless, as had been said above, they already do have a significant magnetic field.
Yep. By the way i forgot to add my answer. If you threw electrons into a accretion (sorry if spellings arent correct) disk, then those electrons will produce a strong magnetic field. But for a blackhole to have a magnetic field, it must have a charge.schwarzschild bhs and uncharged kerr blackholes wouldnt do that.
Big ups for giving Heavyside the credit he deserves! Maybe even a little too much credit... Hail Heavyside! The unsung hero of electromagnetic theory and all the amazing things we've gotten from it! Even the equations describing transmission lines, which Heavyside derived, ended up name the “telegraphers' equations”. Again, not name for Heavyside! Snubs, snubs everywhere!
@@ScienceAsylum @The Science Asylum i didn't know that.( THANK YOU) After your answer i've searched a little and find Materials(mostly cresolic solvent mixtures.) I have another craziest question for you... It is possible that black holes are compressed dark matter after explosion of stars? Similar to explosion in deep water?
Why isn't the wire on the left at 1:20 also shown as generating a magnetic field? And why does the wire on the left move away, instead of the wire on the right move away -- or both move away from each other? Not explained. Very confusing.
1) You are correct. If the wire on the left has a current, then it also affects the magnetic field. I didn't include that because it would have distracted from the point I was making with the graphic. At some point, in any diagram, you have to leave things out for clarity. 2) As far as the wires moving, assume the wire on the right is attached/fixed to the table. Problem solved.
So ,why is it that people are so devastated that we need to save energy badly. I mean, I`m not waisitng it or over-using it. But feels weird why they imply such things.
Some processes that give us usable energy are bad for the environment. Also, the grid can only handle so much electricity draw at once. That being said, I'm sure most of the "conserve your energy" conversations are about saving users money.
Maxwell built a generator that spun continuously once started that produced a voltage at the outer rim of a round copper plate sandwiched between 2 ring magnets and drove a generator which also produced an electrical output but he never pursued it. In the 1980s Bruce de Palma perfected that setup at got 10 kv from that similar setup and he pursued it and died shortly after after releasing his plans to the world. Seems like a generator will also produce electricity if the magnet and copper are spinning together. Good video keep up the good work.
Dude! You're the best. Your videos are amazing... Comical and easy to understand. Also explaining misconceptions (Such as the quantum double slit experiment and the wave collapsing... there's a lot of pseudocscience going aorund and your video is absolutely refreshing in that matter). I love your content! keep up that good work, you crazy son of a gun
So informative as always, thank you. "It's just that some source energies are better for the environment than others." Yes, and I am sorry to say that Australia is still stuck in the nineteenth century regarding the mining and burning of coal. Hopefully we can rise above the lack of foresight from our infinitely uninspiring governments past and present, and move into a brighter, healthier and saner future. Keep up the Good work Nick.

I know this is a really basic point to make, but I've noticed in the past when someone who is attempting their very first coil, they don't realise that the copper wire here is actually insulated and then, don't understand why their coil doesn't work because they've stripped down to a bare copper wire to start their coil.
Science Asylums copper wire has a thin clear lacquer coating to prevent the wire from touching itself.
Yes, correct. Thanks for pointing this out.
In calculus I always heard about the "Heaviside step function" and I honestly thought it was "heavy-side" like heavy vs light and had something to do with taking the value of 1 rather than 0 at 0 until I quite recently (but not today) learned there was a physicist named "Heaviside" who invented electromagnetism and vector calculus.
He's so underappreciated! It just goes to show where _bad_ social skills will take you in life.
Taylor Polynomials is another interesting coincidence where the mathematician's name describes the concept he contributed to mathematics. A Taylor polynomial is tailored to match the function.
My Teacher used your videos for examples. You’re a great teacher.
That's great! I love to hear when my videos are used in classrooms.
I'm a D.A.R.E. instructor and I use your videos all the time in class!! ...Naw just fuckin with ya...
To through internet wifi in universe to be abundant then dark matter and dark energy so that universe doesn't collapse internet wifi in light year fast
You're videos are great! Thanks to you, I decided to study physics
I was curious as to how electricity made stuff work, now I'm watching this at 4 am, learned a lot though
Then this one is going to blow your mind: ruclips.net/video/C7tQJ42nGno/видео.html
Usually it's the magnet that spins, and not the coils. It's easier to extract power from stationary coils. The magnetic field can be created by a spinning coil, but it operates at a lower voltage which can be passed into the rotor by slip rings or a transformer
Didn't expect a video so quicly after the last one.
Currently falling down a physics rabbit hole...
Shame that, we don't learn this in school.
1:03 from the right hand rule it should go in opposite direction, is it true? :O
I was showing electron flow, not "conventional current," so things are backwards.
@@ScienceAsylum oyaaaa btw one of the best channel on yt with all those visualisations worths more than a thousands of letters in the book :D
@@ScienceAsylum so i guess that means that the direction of the magnetic field on that axis doesnt matter for the Lorentz Force? both the conventional current and electron flow in that wire create Lorentz Force in the same direction? (of course it needs to be perpendicular, but already is as seen in video)
How long does it take you to upload please more
I upload twice per month. It's best I can do. These videos take forever.
@@ScienceAsylum thanks for the amazing content
Another great video--sorry it took so long for me to watch this one. Looking forward to the next. :)
That next one is going to be mind blowing. Also, Ben, you're under no obligation to watch my videos ;-) There's no pressure here.
Bless you so much for continuing to spread knowledge 🤘🏼
Jesus is lord😇!
Nuclear power ✔️
It doesn’t get much better then fission until we unlock fusion.
I wish I had a chance to watch these videos when I was a kid... After decades and all technical studies, watching your videos is priceless.
Wonderful explanation! This channel is the Oliver Heaviside of RUclips. On a positive note, the improved YT algorithm has actually provided me with something useful.
I love everything about this and actually learned things that shifted my perspective. :)
"WORK IT! I need a glass of water..." 🤣😂👌
You make science interesting in a way that would have taught me a LOT more in the science classes I was FORCED to take... and for a LOT less money. Being crazy is part of it... all the BEST people are, you know :))
Pls can u make a video explaining what voltage actually is ?!?!?! 🤔🤔🤔
Voltage is actually the potential for charges like electrons in the electric field. A potential is always the difference of energy of the particle at a point compared to the energy at a reference point diveded by the charge itself. So if you multiply the voltage (or the potential) at a point by a charge you get its energy at this point. Or in other words the higher the voltage, the higher is the energy of charge at that voltage.
By energy i mean the potential energy und note that you dont always divide by the charge. For example there is also a potential for the gravitational field which is the difference of potential energy divided by the mass. So in general the potential of a force field in physics is the potential energy divided by the quantity which causes the force. The cause of the force in the electric field is the charge.

The microphone you talk into converts a metal plate's motion into electricity. A magnet provides the field and a coil collects the current. Vibrations from your voice make the mic's plate vibrate, same in guitar pickups where the strings replace the plate. Scream close to a guitar string, and the amp will actually project your voice.
Indeed!
I started my iPad, and your video started on its own...
Your clone must’ve pushed play...
Thank you, pushing clone.
Nick Lucid, you are the best teacher i ever saw and these videolessons are so exeptionally clear, i wish you where my teacher in my school. A pity i am dutch, but the school where you work shall and will without doubt deliver science students noticable above the average, in number ánd level. You are unique on youtube, thats for sure!
Yet, none of them ever wanted to hire me full-time...
Anybody here now??
I cant believe, why there are not much, much more people who had subscribed this channel yet.. Must be up to a million at least...
0:42 “you know what’s coming”
Dope video man, keep up the good work!
Thanks!
i understood great
Me too. Me now know good.
I find this guy to be humorous. Thanks for what you do.
Now I'm experiencing thirst and will perform the required steps to cure this.
TIL: Most power plants are just a very very large water boiler.
Fact.
Omg, i am almost tearing..
It was hard for me to get a full understanding of the magnetic induction for 2 months.. And u just simplified everything for me in less than 7 minutes.. Thank you so much ❤️❤️
Glad I could help! 🤓
one crazy question nick ! imagine if we isolate a black hole ....and start "feeding" ELECTRON ONLY. what will happen if we continue to feed..also consider that black hole also SPIN. will it produce magnetic field also?
Black Holes do have magnetic fields
If they have a charge 👆
@@Private_Duck
If they have mostly electrons, they do have a charge.
I believe it should be plausible. However, getting a black hole charged to the extent that it produces a magnetic field great enough to be used from the distances we can reach would require an immense quantity of charged particles to be sent within it. Nonetheless, as had been said above, they already do have a significant magnetic field.
Yep.
By the way i forgot to add my answer.
If you threw electrons into a accretion (sorry if spellings arent correct) disk, then those electrons will produce a strong magnetic field.
But for a blackhole to have a magnetic field, it must have a charge.schwarzschild bhs and uncharged kerr blackholes wouldnt do that.
Strength are the guys who make things funny and reduce their increase in ado about saying something,Keep it up bro,Well done
1:31 they look so cute from the side view 🤗
Anyone agree?
The clones are the best
The notification of this video magnetised me to the point I started radiating with excitement. So, here I am.
Hello crazy.your videos are best
Genius, speaking that fast, rather speeding up the speech. Our superb minds discern the message even thru the sillinous at the right speed. Thank you
you deserve more, your videos are interesting and easy to understand!, especially for beginners like me =]].
Great content, I just subbed
I wish you were my school teacher
Great video, as always. Thank you !
Glad you enjoyed it! 🤓
I'm like question clone. Pointing out the details. Curious.... Lol
You really simplified the concept for me. I was so confused in class and didn't really get the concept. Thank you
Yes more "to the time line!" haha
Hands down the most underrated channel.
Who’s here from Dr. Stone ?
Big ups for giving Heavyside the credit he deserves! Maybe even a little too much credit...
Hail Heavyside! The unsung hero of electromagnetic theory and all the amazing things we've gotten from it!
Even the equations describing transmission lines, which Heavyside derived, ended up name the “telegraphers' equations”. Again, not name for Heavyside! Snubs, snubs everywhere!
another craziest Question: why there is no short path(short circuit) in coils.
The wires are insulated. They might not have the thick rubber kind of insulation, but they are _coated_ in a thin layer of insulating material.
@@ScienceAsylum @The Science Asylum i didn't know that.( THANK YOU) After your answer i've searched a little and find Materials(mostly cresolic solvent mixtures.)
I have another craziest question for you...
It is possible that black holes are compressed dark matter after explosion of stars?
Similar to explosion in deep water?
Programme for short circuit fire prevention
Nice refresher video here! Been a while since I'd visited these concepts. Look forward to more.
Why isn't the wire on the left at 1:20 also shown as generating a magnetic field? And why does the wire on the left move away, instead of the wire on the right move away -- or both move away from each other? Not explained. Very confusing.
1) You are correct. If the wire on the left has a current, then it also affects the magnetic field. I didn't include that because it would have distracted from the point I was making with the graphic. At some point, in any diagram, you have to leave things out for clarity.
2) As far as the wires moving, assume the wire on the right is attached/fixed to the table. Problem solved.
So ,why is it that people are so devastated that we need to save energy badly.
I mean, I`m not waisitng it or over-using it. But feels weird why they imply such things.
Some processes that give us usable energy are bad for the environment. Also, the grid can only handle so much electricity draw at once. That being said, I'm sure most of the "conserve your energy" conversations are about saving users money.
1:35 it kinda looks like the meme of the average questions fan vs the average patience enjoyer
Maxwell built a generator that spun continuously once started that produced a voltage at the outer rim of a round copper plate sandwiched between 2 ring magnets and drove a generator which also produced an electrical output but he never pursued it. In the 1980s Bruce de Palma perfected that setup at got 10 kv from that similar setup and he pursued it and died shortly after after releasing his plans to the world. Seems like a generator will also produce electricity if the magnet and copper are spinning together. Good video keep up the good work.
And electricity converts to energy, and where it all begins. Thanks for the explanation. I’ve got better understanding now.
I watched this video with no sound and captions.... Nick’s voice resonated in my mind all long the video, even the sound effects... it’s crazy!!!
Just a side note, you explained the basics of an electric guitar.
Dude! You're the best. Your videos are amazing... Comical and easy to understand. Also explaining misconceptions (Such as the quantum double slit experiment and the wave collapsing... there's a lot of pseudocscience going aorund and your video is absolutely refreshing in that matter).
I love your content! keep up that good work, you crazy son of a gun
Thanks! :-D I'm just trying to do my part.
"Work it. I need a glass of water" 😂, don't think my kids will get this one
Did I date myself with that one? 😂
So informative as always, thank you. "It's just that some source energies are better for the environment than others." Yes, and I am sorry to say that Australia is still stuck in the nineteenth century regarding the mining and burning of coal. Hopefully we can rise above the lack of foresight from our infinitely uninspiring governments past and present, and move into a brighter, healthier and saner future. Keep up the Good work Nick.
The missy elliot bit was hilarious
I love your videos Nick. When will your topic of electrodynamics get over. I mean I love this topic, but I want to learn something new too.... Letting everything aside, I just love your videos!!
We'll be taking a break from it soon. I'm getting sick of it too. I want to talk about other things now.
