FANTASTIC video Derek. I'll teeet it in a second. It make me realize that wouldn't there be a type of magnetic terminal velocity for hypoerloop because of Lenz's law?
SmarterEveryDay Lenz's law is responsible for the levitation itself. The speed of such a vehicle would be limited by the additive effect of inefficiencies in generating the levitation, such as the torque applied to each rotor by the slight difference in location of the magnetic fields, friction in the moving parts, air resistance (a vacuum on the scale of a hyperloop would require an insane level of energy and money to maintain), and others.
I'm sure it was the same bag-o-dicks presenting their one way thinking of stupidity like these guys. Too much money being made with some harmful tech that must be produced to keep us living like the caveman.
I cant help but think how this tech could be adapted to bobsledding, at lightning speeds! Copper track, with Tesla Sled, all iced up for hard contact turns. Of course new designs for tracks...
I don’t see a practical purpose for a magnetically levitating “hovercraft”, but if you flip it upside down, I bet it’d make a good induction cook top. I can fly from Florida to Japan in ONE DAY 👍
@@protonjinx that is true. Internal combustion engines are inefficient, but unless you plan on lining the roads with steel plates, a magnetically levitating car is worthless. Mag lev trains are fine, but 1. We don’t have any, 2. They don’t drop you off exactly where you wanna go. I’d like to see hydrogen fuel cells.. most abundant substance in the universe.
@@Hardzinho_Yay maglev trains are fine. I said HOVERCRAFT. A hovercraft is not a train, but like the hover trains, would require a special surface to function, thereby rendering magnetically levitating hovercrafts useless.
That is actually a propulsion system on one of our top secret aircraft. It's older technology but it works. It eliminates the g forces and your speed is incredible.
Now you just need to lay copper through the entire hyperloop... that'll only cost billions and billions of dollars on top of the already insane price tag...
So, in the 1950's, they theorised that the use of electromagnetic levitation could be used for aircraft, around the time that nuclear reactors were being put into submarines. I imagine they would be smart enough to put two and two together by now.
We already have a way to go from one city to another in less than a day. It's called an airplane, and it's not restricted to a track, tube, or anything like that.
Where do copper floors exist though? The problem is that coating the floor with copper is expensive and unsafe. The only applications I can think of for this are bumper cars and maybe some kind of forklift for a warehouse. But we have more conventional means that are way more energy efficient.
Yea it's called induced currents in the copper creating an opposing magnetic field, since the Earth is no where near conductive enough for this effect to work it's basically useless.
@@buckminsterfullerene2294 It will never have the same effect ... The density of the plate is proportional to the weight effect ... (Same effect inside the copper tube and its effect due to thickness of the tube)
Copper powder roads actually do exist, just not for this purpose. It'd actually be better if it was aluminum or gold, or something far more specific and convoluted.
@@gigaus0 : Actually, copper is fine. Though I'd go for aluminum for cost reasons. The bigger issue is that it needs to support a strong enough magnetic field, so a powder mixed with asphalt probably isn't a good choice. I'd go with thin but overlapping plates or something instead.
the last sentence that guy said... "to be able to get to a different city in the same day in my life time would be amazing" or something like that... does he not know about them aero planes?
it might have meant as a ferry : since trains can run on a tight scheduele , at extremely high speeds , but realisticali i think that 840 km/h ( 520 miles/h ) is a maximum above that it'd be impractical to make ordinary passangers handle the accelleration / you wouldn't enjoy the advantages of going at high speeds ... and BTW the Hyperloop is garbage : you simply can't make a low pressure chamber with that size , the tech isn't there yet ...
I really would like to know how much energy is used to levitate since there that counter torque. and how much more efficient would that kind of transportation be compared to losses due to friction of e.g. ball bearings.

Not quite. Some people could misunderstand this comment and think that neodymium magnets are useless and therefore "traditional" magnets should be used. For each application obviously you have to choose the material, geometry, system, etc. adequate. In this case, if you want to use SUPERMAGNETS (that is, magnets made with RARE EARTH, such as neodymium-iron-boron Nd2Fe14B), you must choose another material. That material is the intermetallic compound Samarium-Cobalt, SmCo5, which has magnetic properties almost as good (approximately 85%) as neodymium magnets, and whose critical temperature is about 2.5 times higher, even better than the critical temperature of many traditional ferromagnetic materials.
@deconvertedguy well tbh its not justified why we have poles some say do to molten core which is mostly metal and its spins which induce magnetic field. but molten lava is way too deep inside the earth so thats out of the picture
@@ayushsrivastav9055 The world has a lot of conductive metal, but most of it is heavily insulated and it isn’t NEARLY densely packed enough to induce an appreciable magnetic field.
You know, I'm not sure about practical consumer uses, but this would be perfect in large warehouses. Imagine a frictionless pallet jack or rolling safety ladder
Yeah but imagine how much easier it would be if it glided effortlessly after that initial push, you'd double your efficiency. It wouldn't be too hard to add a brake to this, surely they can come up with something
It wouldn't make my job easier at all. Pallet jacks are motorized and it would be hard to add a brake, how do you stop something that's levitating? Not to mention the double pallet jacks I use weight more than a car when they're loaded up.
But I don't get this: the point of levitation is to get rid of friction, allowing greater speeds (and also less wear), but here we just saw that there is resistance to motion and a lot of heat produced. And if you ever had an aluminium block and a strong magnet, you can try moving the magnet quickly over it and see how strong the pull is. So, is the net effect still better than using wheels that have very good ball bearings?
Ciroluiro with maglev, most of the electromagnets used are high temperature superconductors that are Flux pinned at certain heights. They generate no heat and act almost like magnetic mirrors. All the energy required is maintaining enough heat extraction such that ambient heat diffusion doesn't move the plate above the critical temperature.
Komninos... hyperloop may be a pipe dream for some reason or another, but it's worth a try even if it fails... we'll still learn a ton. You sound like the naysayers in the 60's with their "spaceflight is impossible and a waste" BS... even if it were a complete failure, which it obviously wasn't, we still gained world-changing technology that is highly practical today just from trying.
The drag is speed dependent which mean if you move that magnet on the aluminum block fast enough you'll actually experience reduced drag and more lift.
Gee, technology moves fast. City to city travel, can be done these days, easily - a couple of Maglev trains are running, one of them over a 150 mile long track ( Tanjin to Beijing ; another from Shanghai Airport to Shanghai city 19 miles ; each is a commuter service. Japan, also runs Maglev train services, & that's about it, all other trains are steel wheels, or you either fly, or cruise via sea.
uh... he asked how much it weighs, not what its mass is. The correct answer is-- it weighs 467 N. Maybe learn your precious metric system better. You guys screw up mass and force more often than you get it right.
@@HollywoodF1 The units of mass and weight are generally used interchangeably anywhere on the earth's surface, as the discrepancy between the force of gravity at sea level and, for example, mt everest is negligable.
@@HollywoodF1 kilograms is unit of weight too i mean r u intensionally doing his..unjust look stupid noone wighs things in newtons except physicist.i mean..even if u say 10kilo thats still correct
I really want to see this happen, but a problem immediately comes to mind: you need a power source of some kind. Maybe it's possible with some kind of capacitor since the moment it gets off the ground, there would be a lot less friction to contend with and it could probably keep its momentum like a classical beyblade. Goddamn, can we get Smarter Every Day or Stuff Made Here or someone similar on this?
Or made of copper sheets... then thieves will be tearing up the "roadway" to sell it for as scrap for dope... might as well call it the "dope-ways". lol
When I was 17, I posted a question on 2 different physics threads trying to understand magnets, and what would happen if you could disturb the flow of the magnetic field. Not only did people not really answer, but a bunch of ”professors” (however much weight that title holds on the forums i do not know) shut the 17 year old me down so freaking hard telling me im digging in the wrong spots and that this information is useless, ”otherwise, others would have already thought about it”. Now this guy right, 6 years later is telling me how they actually achieved this prior to me even posting the question, and the tech is being used in the large hadron collider... such a freaking shame tbh.
That’s why you don’t allow your ego to be hurt by the interweb denizens. For every one person you find who is good support, there’s 100 naysayers who will beat you down...and 1000 who’ll say, “duhhh...wut iz u ta’kin’ ‘bout?
Instead of physically rotating a bunch of magnets, couldn't they just use an array of coils energized in sequence to produce the same fields? (Think along the lines of induction motors.) A couple sets of transistors in parallel (to handle the current) to switch each coil, and then you have something solid-state with no moving parts. Now just make that copper plate into an inverted V shape, and bank each pair of magnets and it should self-center to make a working track of inverted-V sections. Still this system isn't that efficient if anything has to hover in place without moving, too much of that energy is wasted as heat from the resistance of the eddy current.
There is a minimum amount of time that the field lingers before it dissipates and you can actually charge the next configuration. Basically the same reason why Gause cannons aren't a real thing outside of small scale laboratory demonstrations and sci-fi stories.
Current requirements, switching and current lag, would probably negate their use in mag-lev systems. Not to mention the increased initial cost and complexity.
Hyperloop is just maglev but more expensive and less return. Most of the resistance comes from the wheels so removing the wheels gives you a big boost to efficiency. If you want to reduce air resistance simply make the train longer so you can move more mass with less surface area. That's why maglev exists while hyperloop remains a fantasy. Besides, existing trains already have a very good efficiency for their cost, that's why we use them so much. Their ability to use electricity also makes the a perfect target for renewable power.
Visited Vanderbilt Univ a little of 5 years ago and saw one very similar in action. Pretty cool. Then they showed me the video that inspired them and it was one of my videos from 10 years ago.:) Still amazing to see it work. Kudos on the video.
Alan Hatch well it's still possible even without the sheet, you just need to create a strong enough magnetic field and this thing could perfectly work, you don't need to lay down copper plates over a huge territory for it to work.
@@Barefoot_Joe I think that's probably because Britain is small and hilly. The benefits of lower friction add up over longer distances that we don't really have, so it makes more sense to use a faster but more conventional train.
@@Barefoot_Joe also the British one used an old technology, and got shut down because it worked so well & worn out so little they didn't bother manufacturing spareparts until it's too expensive to do so
Well, first get the 200 million atmosphere pressure on the super conductor material... And then see if you can spin that material and the pressure container around like those permanent magnets....
if i'm not mistaken you don't bring temps up you bring them down @ sub zero where some materials are natural superconductors but we gone have to figure out how to turn natural resistor like stone's into conductors No?
@@yinyang1217 I did this before the universe was created. heard a big "bang" and next thing i new it was billions of years later and i was typing a stupid youtube comment.
I screwed around with this in middle school a bunch of guys and I thought it would be funny to sping magnets on a motor to use as a method of power transmission, never thought of using it this way even after learning about the moving a magnetic field thing in high school
If you used this in a house to move certain things efficiently, what if you took the heat generated on the floor, underlayed the floor with water so that water is boiled for steam to be produced and then the steam is then circumvented into a steam engine to gain back some of the used energy. The floor would also have some form of heat resistant coating so you can step on it too.
Are you forget the fact that the copper warms up to the point where it will boil water? Imagine traveling across a surface that can burn you and horribly disfigure you at any point. Yeah, not just yet.
Main Problem with them are 1. It needs a LOT of power 2. It makes a LOT of heat. 3. They break easy and aren't cheep to make. but if we got over those problems then they would start to see more use.
How would one go around calculating lift? What would one do to increase it? Stronger magnets? More RPM? Both? Is it possible to generate less lift on front side in order to "slide forward"?
There are little mice who are trying to catch a piece of cheese, and the have been trained to wear non-slip sneakers. This force is connected to the magnets by means of a six speed transmission. in case any mice catch the cheese and extra energy is released.
@@ZimaletaMotors Depending on how hot you get it, you might be able to boil water underneath it and then push that through a steam turbine. Maybe. IAN an electrician, engineer, or terribly smart person.
Man, I can't wait for future generations to be able to travel to different cities in one lifetime. What exciting times we live in.... I thought that technology only existed in the Flintstones documentaries.
If by tech, you mean electromagnetism? Yes. If by tech, you mean spinning magnets? No. I’d argue this is relatively more complex than a RG. RG’s are simple from an electromagnetic standpoint, scaling them to do what the Navy wants is what complicates things - this complexity mostly revolves around the amount of power certain electronic components can withstand.

You sound like the naysayers in the 60's with their "spaceflight is impossible and a waste" BS... even if it were a complete failure, which it obviously wasn't, we still gained world-changing technology that is highly practical today just from trying.
The drag is speed dependent which mean if you move that magnet on the aluminum block fast enough you'll actually experience reduced drag and more lift.
Woah. Imagine in the future when I can travel from one city to another city in one day!
Gee, technology moves fast.
City to city travel, can be done these days, easily - a couple of Maglev trains are running, one of them over a 150 mile long track ( Tanjin to Beijing ; another from Shanghai Airport to Shanghai city 19 miles ; each is a commuter service. Japan, also runs Maglev train services, & that's about it, all other trains are steel wheels, or you either fly, or cruise via sea.
105 pounds = 48 kg,

uh... he asked how much it weighs, not what its mass is. The correct answer is-- it weighs 467 N. Maybe learn your precious metric system better. You guys screw up mass and force more often than you get it right.
@@HollywoodF1 The units of mass and weight are generally used interchangeably anywhere on the earth's surface, as the discrepancy between the force of gravity at sea level and, for example, mt everest is negligable.
Thaaaankk youuuu😌😌😌😌
@@HollywoodF1 kilograms is unit of weight too i mean r u intensionally doing his..unjust look stupid noone wighs things in newtons except physicist.i mean..even if u say 10kilo thats still correct
@@HollywoodF1
So when the question was for the weight, why is the answer in pounds? This is a mass unit too.
Imagine implementing this technology into beyblades
I really want to see this happen, but a problem immediately comes to mind: you need a power source of some kind. Maybe it's possible with some kind of capacitor since the moment it gets off the ground, there would be a lot less friction to contend with and it could probably keep its momentum like a classical beyblade.
Goddamn, can we get Smarter Every Day or Stuff Made Here or someone similar on this?
the levitation effect would be similar to that one beyblade in Russian team which floats due to waves
Lmfao of all the comments.

When I was 17, I posted a question on 2 different physics threads trying to understand magnets, and what would happen if you could disturb the flow of the magnetic field. Not only did people not really answer, but a bunch of ”professors” (however much weight that title holds on the forums i do not know) shut the 17 year old me down so freaking hard telling me im digging in the wrong spots and that this information is useless, ”otherwise, others would have already thought about it”.
Now this guy right, 6 years later is telling me how they actually achieved this prior to me even posting the question, and the tech is being used in the large hadron collider... such a freaking shame tbh.

Instead of physically rotating a bunch of magnets, couldn't they just use an array of coils energized in sequence to produce the same fields? (Think along the lines of induction motors.) A couple sets of transistors in parallel (to handle the current) to switch each coil, and then you have something solid-state with no moving parts.
Now just make that copper plate into an inverted V shape, and bank each pair of magnets and it should self-center to make a working track of inverted-V sections.
Still this system isn't that efficient if anything has to hover in place without moving, too much of that energy is wasted as heat from the resistance of the eddy current.
So a conventional maglev system?
Split an Eve
Save an Adam..
There is a minimum amount of time that the field lingers before it dissipates and you can actually charge the next configuration. Basically the same reason why Gause cannons aren't a real thing outside of small scale laboratory demonstrations and sci-fi stories.
@@megadeathx Hate to break it to you but the US navy has a fullscale railgun in working order.
Current requirements, switching and current lag, would probably negate their use in mag-lev systems.
Not to mention the increased initial cost and complexity.
Wait, isn’t the hyperloop just a billionaire boondoggle that would be a dangerous if any length were ever built?
Hyperloop is just maglev but more expensive and less return.
Most of the resistance comes from the wheels so removing the wheels gives you a big boost to efficiency.
If you want to reduce air resistance simply make the train longer so you can move more mass with less surface area.
That's why maglev exists while hyperloop remains a fantasy.
Besides, existing trains already have a very good efficiency for their cost, that's why we use them so much. Their ability to use electricity also makes the a perfect target for renewable power.
@@ViciousVinnyD yeah, explosive decompression and pressure waves are no joke.
Well you sure won't be making a UFO anytime soon unless you feel like flying over a copper plate all the time
Technically it won't be an ufo cause we will know what it is
That’s cute but I doubt UFO’s use magnetic fields in this fashion.
Elon Musk wants to:

robb maier uhhh wtf?
Visited Vanderbilt Univ a little of 5 years ago and saw one very similar in action. Pretty cool. Then they showed me the video that inspired them and it was one of my videos from 10 years ago.:) Still amazing to see it work. Kudos on the video.
The heating effect is called Magnetic Induction which is what makes Induction Cooktops work.
Edy current ?
I was excited until I noticed the copper sheet.
Exactly, there is thickness to it too which (I am guessing) matters
Alan Hatch well it's still possible even without the sheet, you just need to create a strong enough magnetic field and this thing could perfectly work, you don't need to lay down copper plates over a huge territory for it to work.
Alan Hatch yeah when I noticed that I thought, Oh sheet
(get the pun?)
It's a small price to pay compared to the benefits
BINGO!
So it's like those magnetic trains that the ENTIRE planet has outside of the US.
yup
yup yup@@jeffchilds8050
Only a couple of countries have Maglev, and the country that invented it (UK) doesn't use them and never has, it should tell you a lot.
@@Barefoot_Joe I think that's probably because Britain is small and hilly. The benefits of lower friction add up over longer distances that we don't really have, so it makes more sense to use a faster but more conventional train.
@@Barefoot_Joe also the British one used an old technology, and got shut down because it worked so well & worn out so little they didn't bother manufacturing spareparts until it's too expensive to do so
Sorry I was too busy watching the slomoguys video

2020 here, what do room temperature high pressure superconductors mean for this technology?
Well, first get the 200 million atmosphere pressure on the super conductor material... And then see if you can spin that material and the pressure container around like those permanent magnets....
With superconductors you wouldn’t need any spinning, but the ground would need to be covered in magnets.
That was disappointing. Unless we make copper roads, this isn't going to help making hoverboards x)
At superconducting temperatures, everything becomes magnetic. Just have to bring superconducting temperatures up, a lot.
+Lagrange Si
Thats not true at all, however you can use any conductor.
if i'm not mistaken you don't bring temps up you bring them down @ sub zero where some materials are natural superconductors but we gone have to figure out how to turn natural resistor like stone's into conductors No?
Actually it means all we have to do is make copper roads if we want hover boards
Nate Well what do you think happened when we needed roads for cars

I screwed around with this in middle school a bunch of guys and I thought it would be funny to sping magnets on a motor to use as a method of power transmission, never thought of using it this way even after learning about the moving a magnetic field thing in high school
If you used this in a house to move certain things efficiently, what if you took the heat generated on the floor, underlayed the floor with water so that water is boiled for steam to be produced and then the steam is then circumvented into a steam engine to gain back some of the used energy. The floor would also have some form of heat resistant coating so you can step on it too.

Copper solar freaking roadways!
Brilliant!
And with solar panels so it pays for itself
Are you forget the fact that the copper warms up to the point where it will boil water? Imagine traveling across a surface that can burn you and horribly disfigure you at any point. Yeah, not just yet.
@@StadiaTime - cool it with a liquid on the underside and pump that hot liquid to Russia to heat people's homes
I had to laugh! What a fail the solar roadways were.... Unbelievable!
A lot people love science. Doesn't mean they understand it thou
the fact one of the guys worked on hyperloop one does not give me confidence this will be practical and usefull lololol
Can you explain to me what you just said
Main Problem with them are 1. It needs a LOT of power 2. It makes a LOT of heat. 3. They break easy and aren't cheep to make. but if we got over those problems then they would start to see more use.
@@evanschmitt2802 you forget they need a big slab pf copper plate beneath them. so your limited to the space you place an inch of coppersheet

How would one go around calculating lift? What would one do to increase it? Stronger magnets? More RPM? Both? Is it possible to generate less lift on front side in order to "slide forward"?
I don't recall the lift stuff, but the rest of the stuff is "yes". Look up stuff like "linear induction motor" and "magnetic river" for more.
@@absalomdraconis Awesome, thank you.
I couldn't imagine wasting my life by working for a hyperloop company.
How fast do the magnets spin (like in rpm's)?
There are little mice who are trying to catch a piece of cheese, and the have been trained to wear non-slip sneakers. This force is connected to the magnets by means of a six speed transmission. in case any mice catch the cheese and extra energy is released.
That's why UFO's or flying saucers spin 🤔
Is there a way to absorb that heat and redirect it to produce energy?
Jack Daniels lol my question exactly, I think there’s many uses for the heat that’s generated, it can be used to generate electricity for sure
@@ZimaletaMotors Depending on how hot you get it, you might be able to boil water underneath it and then push that through a steam turbine.
Maybe.
IAN an electrician, engineer, or terribly smart person.
Perhaps having the underside of the copper sheet connected to an array of thermocouples might do it.
wonder if cats would sit on this like they do on Roomba's..?

Rick and Morty passed away so what you really need to go see them is a cofffin💥🤭😂😂
That's pretty wild. Is this also the tech that moves a projectile in a rail gun?
If by tech, you mean electromagnetism? Yes. If by tech, you mean spinning magnets? No. I’d argue this is relatively more complex than a RG. RG’s are simple from an electromagnetic standpoint, scaling them to do what the Navy wants is what complicates things - this complexity mostly revolves around the amount of power certain electronic components can withstand.
