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.

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 лет назад

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?

@sevanz3490 7 лет назад

I think it will spin longer. however, the magnet not being perfectly stable, will create some sort of resistance

@LancerFanClub 7 лет назад

@xtramoist9999 7 лет назад

Does the magnetic field itself involve friction? Like, if you could somehow avoid all the other variables would the magnetic field eventually slow the spinner down?

@deepakkudari2348 4 года назад

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.

@raphaelklaussen1951 2 года назад

Almost, there is more to it. Unless the top spins without wobble and is perfectly smooth and perfectly symmetrical, it will radiate em energy and will eventually stop.

It can’t go in a straight line yet it wants to. It’s like what happens when you let go of a bag of something we’ll spinning the bag flys out of your hand. The closer you bringing your hands in the faster you go but the faster you slow down because your body wants to go in a straight line the force of that gets stronger when you bring your hands in. But when you bring your hands in it also creates more friction.

@thom1218 7 лет назад

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 лет назад

super interesting, thanks for commenting with this

@firefly618 7 лет назад

This is the correct answer. Also, the initial spinning was quite lousy.

@kevinmathewson4272 7 лет назад

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 лет назад

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.

@keantoken6433 6 лет назад

So perhaps to make it spin longer you could replace the washers with a non-conductive and perhaps non-magnetic material? Or cut slits in them to break the eddy current paths?

The rotation in magnetic field induces currents in the gyroscope itself, they are dissipated through heat. I think the spinning time actually has to do with the internal conductivity of the gyro. Chill it down (liquid nitrogen might do it :P) and it will spin much longer. Or maybe not ?

@mabus4910 6 лет назад

Mihai-Andrei Caţan I think it eventualy will tilt due to earth rotation.

@santerisiiranen3924 6 лет назад

Yeah that is much better explanation. I think this has nothing to do with friction. It's about heat produced by eddy currents inside the gyro and the round magnet that slow the gyro down.

@Boomproof 6 лет назад

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.

@shortbutlucky 6 лет назад

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.

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.

That should prove you that, the first imperfection in the run will end up aplified and rip the thing...and if you will say that it is caused by the friction between magnet and chamber, well, glew that in place and the static friction won't dissipate energy!

@dantonspivey 3 года назад

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 лет назад

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.

@somethingelse2740 6 лет назад

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! I used to be an avid RC guy, it is a great hobby and you'll meet lots of nice people and share knowledge if you join an RC club. Peace! And keep those rotors and props balanced!

@highrevs6110 5 лет назад

No such thing as a perfect vac. Secondly, vertices axis changes must surely absorb energy and slow the gyro quite quickly?

@vincentrobinette1507 5 лет назад

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.

@SeattlePioneer 5 лет назад

I agree, the losses being caused by energy lost to procession keeping the top up. But I also think that the magnetic top rotating in a magnetic field will cause electrical resistance and that energy to move the electrons is coming from the rotational energy, just like cranking a generator.

@MissChanandlerBong1 2 года назад

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.

@GrumpDog 5 лет назад

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 лет назад

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.

Spinning in presence of magnetic field will produce Eddy currents and force will act on current carrying gyroscope present in magnetic field thus it gets damped

@MarkTillotson 6 лет назад

Ferrite is not an electrical insulator, so it has eddy current losses - but a lot less than metals. The thin chrome plating on the toy itself is unlikely to be as significant. And there's still residual air to provide friction (is viscous drag linear with pressure? I'd imagine strange things happen with long mean free paths).

@a1919akelbo 6 лет назад

Though eddy currents do have an effect its extremely minimal, the reason it slows is due to the instability and shaking burning off all the energy

@wedmunds 6 лет назад

Ideal inductors do not dissipate power. That said, unless the top was made of a superconductor, there will be resistance and that small resistance will convert a tiny amount of electrical energy (from eddy currents) to heat. But all things considered, the amount of energy lost due to eddy currents is still extremely insignificant.

About the spinning top in a vacuum in orbit : I think there is also the tidal effect that will destabilise it : the spinning will make it want to stay on the same plane while the tidal effet will want to make that plane change. That is why after a long time an object like the moon end up showing the same side to the other. A not spinning top will end up having one side always pointing toward the center of the Earth. And there are rules of axis or maxi/mini cross section to calculate probabilities of preferred orientation.

You've described a innovative hybrid system combining hydraulic pressure, magnetic levitation (maglev), and rotational energy harvesting! Let's break it down: 1. _Hydraulic press_: Applies pressure to the rotor, causing it to spin faster as it approaches the maglev base. 2. _Maglev base_: Utilizes magnetic forces to levitate and rotate the rotor, reducing friction and maximizing efficiency. 3. _Magnetic rotation_: The maglev base's magnets create a rotational force on the rotor, driving it to spin. 4. _Generator_: The spinning rotor is connected to a generator, converting the mechanical energy into electrical energy. 5. _Compression and torque_: As the rotor compresses the magnets, its spin speed increases, generating more torque and electrical output. To optimize this system: - _Heavy rotor_: Indeed, a heavy rotor is necessary to drive the generator's shaft and maintain momentum. - _High-strength materials_: Use durable materials for the rotor and maglev base to withstand the forces and stresses involved. - _Efficient generator_: Select a high-efficiency generator to maximize electrical output from the mechanical energy input. - _Precision alignment_: Ensure precise alignment of the maglev base, rotor, and generator to minimize energy losses and optimize performance. - _Control systems_: Implement control systems to regulate the hydraulic pressure, maglev field, and generator output to achieve optimal operation and safety. This innovative design has the potential to achieve high efficiency and power output by harnessing the advantages of hydraulic pressure, magnetic levitation, and rotational energy harvesting.

@deusexaethera 5 лет назад

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.

@SeattlePioneer 5 лет назад

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.

Perpetual motion idea: If the top was or had a lightweight balanced wire wheel like a dreamcatcher could you use magnets placed on the rim to keep it going using magnetic repelling force, inertia and maybe gravity? The inbound rim magnet would feels "compression" but the inertia keeps it moving till it repells by getting a slight inertia boost or lift to use gravity aswell, or maybe not? You already reduced friction! Got a vacuum chamber! There might be a high degree in magnet engineering we haven't realized yet.

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. But thats not whats stopping it. its the residual air inside the chamber that gets left behind.

Would the box on the outside weigh the same thing with the box on the smaller box inside the larger box or would it feel like it weighs less?

Ok. Suppose the magnet in the base was spinning same direction at same rpm(or close to). That would eliminate magnetic field friction.

Yes, this is true technically but generally people ignore these factors. As a title of "Will a Levitating Gyroscope Spin For A REALLY LONG TIME in a Vacuum Chamber?" does not sound as clickbait, this experiment demon straits if the gyroscope can significantly spin longer until the factors that you considered are put into context. The person in the video is wrong about the friction entirely, as this will happen later on. What really happens to the magnet is that the gyroscope was not on its absolute horizontal axis, as this is extremely difficult to do. Because of this, the force of the magnetic field is not distributed evenly on the edges of the gyroscope, this causes a increasing oscillation in amplitude of the distance to the magnet and this has proportional correlation to the strength of the magnet (obviously). SIMPLE ANSWER: The fidget spinner doesn't slow down, it looses balance. So, the magic rocks (magnets) make it loose control because the fidget spinner is near impossible to be spun horizontally.
