In this video I put a levitating gyroscope in the vacuum chamber to see if it will spin forever without any air resistance. This has been requested many times by my viewers, and I have always wondered what happens to a levitating spinning disk in a vacuum chamber. I show you how the levitation woks and I also give you some tips on how to do it if you get one of these levitating disks.
Here is a link to the gyroscope from Banggood.com:

Hi everyone! I wanted to mention a few things that I missed in the video. First, one of the main reasons it stops that I left out completely is called gyrsocopic precession. Meaning that gyroscopes will tip over due to gravity, but just very slowly. So, since the disk was not directly straight to begin with it eventually tips over. This could be the main reason that it stops so quickly and I didn't even mention it! Also, the magnetic friction I talk about in the video is not actually the base sliding, but more the magnetic domains shifting causing friction. And finally I didn't mention eddy currents because the shiny disk is actually plastic and the magnets are ceramic. But there are two metal washers on it that could have some eddy currents. This also adds in a damping factor. I always learn more than I knew to begin with from my own videos!

@brandonkeffer5752 7 жыл бұрын

Since there is negligible air in the chamber to cause air resistance and the magnetic friction is not a large factor, is the friction being cause by the angular momentum of the gyroscope opposing gravity?

I think it'll stop because of 2 reasons. First one being that it's impossible to create a complete vacuum. So there would be a small amount of air resistance which will contribute to it's fall. Second of all the magnets repulsion is not only causing the top to levitate, it's also resisting some of its motion which will eventually decrease the kinetic energy of the top and it will fall.

It will stop because energy is used by procession to keep the top upright, and this energy comes from slowing the top, which will eventually collapse. Secondly, this magnetic top is rotating in a magnetic field, which means that electrons are sloshing back and forth from the rotational speed much like in a generator. the flow of electrons is consumed by resistance and turned into heat. Just like with a generator, it takes energy to move those electrons, and that will come from the speed of the top, causing it to collapse. I suggest that the two major ways energy is consumed in this system is 1) procession and 2) electrical current flow and resistance.

Could put a mark on it to measure its RPM, use that as a baseline for how fast its spinning and how much speed its loosing over time. Averages over multiple tests in Vacuum chamber vs open air will give you the amount its being slowed by friction with air. If you can find a way you can spin it up while under vacuum and to a controlled velocity it would be even better.

The camera frame rate might not be fast enough to measure that. He could just calculate the average duration of repeated experiments with the vacuum chamber turned off then with it turned on.

@thom1218 7 жыл бұрын

It actually has nothing to do with base magnet moving or any physical friction of any kind (except air molecules from the imperfect vacuum). Eddy currents induced in both the top and magnetic base via the rotation magnetic field dissipate the top's energy in the form of very small amounts heat. Anytime there's a rotating or moving magnetic field, small electrical currents will be induced in many materials, even ceramics.

@kevinmathewson4272 7 жыл бұрын

The top wants to spin in its plane, and the base magnet wants to tilt the top. Every time the top resists this tilt, it spends energy keeping itself aloft by pushing on the base magnet. this interaction saps energy from the spin, I would guess, long before the eddies make any noticeable dent.

@thom1218 7 жыл бұрын

If you compare those tilts to a bouncing ball, then, due to compressive friction (perhaps this what action lab meant), then each push by the top against the base would not receive a push back with 100% of the opposite force, therefore draining energy. This is absolutely plausible. However, no "moving" of the base (i.e. overcoming the coefficient of friction) is going here.

@shortbutlucky 6 жыл бұрын

This is scientifically accurate. Friction by definition requires direct contact. The explanation in the video is a good faith attempt, but is incorrect. If the bottom and top magnet were spinning together in locked sync through alternated fields, the friction of the bottom magnet would indeed cause a magnetic moment on the spinning top and slow it down, but since the bottom is stationary and the fields are not alternating, it’s likely that the metals in and on the spinning top are producing eddy currents as the metals move through the underlying field. To a lesser degree, any remaining air molecules in the chamber will still produce a friction force on the spinning top. If you were to magify the strength of the magnets significantly, you would be able to detect a temperature increase in the top due to the resistance to motion imparted by the eddie currents. See videos on inductive heating to see this in action, and as you mentioned, a magnet slowly falling through a copper pipe is another good example.

@Boomproof 6 жыл бұрын

You are probably right. Just read your comment and made me think of it, electric induction in the gyro generates an opposite poled magnetic field that would generate magnetic friction (N-N, S-S). In essence it's the idea behind the Tesla generator, or commonly known as AC generator. You use this repelling force to induce currents in coils, wich by themselves produce an opposed magnetic field wich's strength is derived off the initial magnet's strength at the core axis of said generator and the number of windings souch as geometry (distances, number of coils, etc) of the system. This sets also the maximum output possible in a generator, being the melting of metal due to internal electrical overfriction your limit; this is given by the diameter of your coil winding thickness. In the case of this gyro, the currents are incredibly low, so my guess is that's why it takes relatively long for it to tip. In a 0-gravity scenario it would probably spin for a felt eternity, as for radiation could have an effect in the long run. Now, inside a faraday cage , floating in 0 gravity... it would spin 4 ever.

@vincentrobinette1507 5 жыл бұрын

You're exactly right, but it's because as the axis changes, the magnetic field strength changes. That causes eddy currents to be induced in the metal disc, which puts a electrodynamic drag on the top. That's why there was practically no difference in spin time in or out of the vacuum chamber. I do realize that by the time he got the vacuum pulled, it had already lost much of its momentum, but the bulk of the loss is exactly what you said.

The slowing of the spin in the vacuum, or in space for that matter, is not substantially due to friction, not due to the molecules surrounding it. Whenever you have a non-constant magnetic field, eddy currents are set up in conductors, and fluctuating magnetic fields are set in magnetic materials. The top has a magnet in it which causes a fluctuating magnetic field when it spins. The magnets in the base are also pieces of ferromagnetic material, and so the fluctuations from the top cause dissipation in the base magnets. Also, the spinning top experiences a changing magnetic field from the base magnets, which also causes dissipation. I think if the top and base were both superconducting, it would spin a really long time, but not forever, because the while superconducting electrons dissipate no energy, there are still some regular electrons in the material which feel a tiny bit of the AC magnetic field so will eventually dissipate the energy. Thanks to my brother Brett for his help with this explanation.

@AeroCraftAviation 6 жыл бұрын

Well it won't spin forever because it is not spinning perfectly level so some of the rotational force is being transferred into an oscillatory force, and so it loses a little bit of its momentum every time it oscillates, and since it has mass, and mass is simply a measure of how much force is required to move an object in a vacuum, the gyroscope would slow down little by little because it's mass is constant but it's rotational momentum depletes.

Way to go Copterdude! You are the first one to answer correctly and I actually made a youtube account so I could post this because you made me so happy that at least one person in the world is not a numbskull. The imbalance in the flywheel is using energy every time it wobbles, the limited energy of the spin runs out gradually and the wheel loses speed until it topples. Of course the not perfect vacuum had a small effect, but not near as much as the wobble. Keep up the critical thinking and the RC fun!

While obviously you can't make something spin forever, and even the magnetics in this case generate a friction.. I'm sure you could improve your results significantly, by starting the top spinning inside the vacuum after it's already at full-vacuum, rather than starting at full atmosphere and then turning on the pump.. Although that would require a complicated mechanical spin&release system built inside the chamber too. lol

@SeattlePioneer 5 жыл бұрын

No. It will stop because energy is used by procession to keep the top upright, and this energy comes from slowing the top, which will eventually collapse. Secondly, this magnetic top is rotating in a magnetic field, which means that electrons are sloshing back and forth from the rotational speed much like in a generator. the flow of electrons is consumed by resistance and turned into heat. Just like with a generator, it takes energy to move those electrons, and that will come from the speed of the top, causing it to collapse. I suggest that the two major ways energy is consumed in this system is 1) procession and 2) electrical current flow and resistance.

I nearly got one of those but I got a Levitron instead. It's a lot of fun because you can put things on it like a model or anything that is non-magnetic and not too heavy. The base will levitate the magnet disc almost indefinitely as long as the base is plugged in to a power supply. But the disc will slowly start to rotate after a while. Eventually it spins faster and faster until it becomes too unstable and smacks into the base. I guess it's because the field from electronically controlled coil inside the base exerts some rotational energy as the field is constantly being adjusted to keep the disc levitating. It's a really cool device because it will levitate the disc in place even if you slowly tilt the whole thing over to 90 degrees.

that is the definition of a PRERFECT vacuum. his setup is nowhere near a perfect vacuum. there is still some (if minimal) air inside the chamber. light waves in fact, can move an object, (by extension able to slow one down) since it has momentum.

1. Magnets run out of power 2. There is no such thing as a perfect vacuum 3. Levetating something with a magnet is like pushing every single part of this something, you are still pushing it, very little but still you are causing friction in the system. 4.There can't be anything that is eternal, every material will be dust in a very long time, and dust will separate into atoms, and them into quarks and so on. 5. Abbey the laws of thermodynamics. 6. Gravity creates friction.. so it will be slowed down slowly. 6 reasons why this can't be an eternal system, even in perfect vacuum and stuff like that.

Rethlitek hm, not quite solid on a lot of these... some are correct though it doesnt have a terrible lot to do with the video. 1) is correct, but demagnatising a magnet takes way longer than the few minutes in the video. 2) is also correct, but the small friction losses to remaining air arent that important here, even in 99.99999% vacuum, it would stop due to things like Induction (see Eddy currents if you wanna learn more about it :) ) 3) is formulated a bit strange for me (sorry, english isnt my main language). as he explained, it looses energy becouse the big magnet below begins to move against the table and that creates friction. Magnets alone dont create friction just by repulsing something. 4) i disagree on you with that one. sure, lots of materials degrade. but they wont just turn into atoms by themselfs without any external energy. it takes tons of energy to split things into atoms, and even WAY more to get them to split into quarks. (as you said in your point 5 (which is correct) , it has to do with Thermodynamics on a larger scale with entropy and Quantum Physics for the quarks). im not quite sure what you meant with 6). I dont know of any way Gravity itself creates friction. apart from pushing stuff together of cause. although maybe i just dont know one, so feel free to show me. didnt mean to be mean or anything. im just trying to get people a better understanding of Physics if they are interested, since i work in Physics :)

No, it won't spin forever. The gyroscope is a spinning magnet, meaning it is interacting magnetically with everything around it, including the Earth's magnetic field, and that drains its kinetic energy. Also, even if it could spin forever, it still wouldn't be a perpetual-motion machine, because you're having to constantly input energy into the system by operating the vacuum pump to maintain the vacuum that allows the gyroscope to spin without friction. ANY input energy after starting the process will invalidate claims of perpetual-motion.
