- 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!
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 will spin longer. however, the magnet not being perfectly stable, will create some sort of resistance
The Action Lab I think it will stop because it wasn't completely stable so it will flip
Well, it could also be from gravity, well , the pendulum at least it just attracts it to a stop
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?

Lesson 5
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.
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.
SO TRUE!!! 😎 You, That homie!
3 angular momentum it’s basically pulling on its self. It’s center of gravity is to center.
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.
Just theory. ??
So far nobody mentioned the energy loss induced by eddy currents as result of a conducter moving in an magnetic field

Hmmm
The slowing isn't from the big magnet moving. The processing top creates a changing magnetic field that sets up tiny electrical currents ('eddy') in both objects, which then gets converted into heat and radiated away through infrared.
ghosttwo2 yeah he didn’t give a good answer
ghosttwo2 But those currents create opposing magnetic fields and it stops after some time right?

The little spinning disc is made from a magnet and some metal probbably. If it's conductive, it creates electricity, so that's probbably slowing it down too.
Tazer counter induced current... nice perception
+Tazer that is true but it is ceramic magnet and plastic casing. Although the washers on it were metal so that has a little impact
The Action Lab the eddy current contradicts the motion, it's used as a way of damping an ocillation.
Tazer this may also be impossible as so far no one person has successfully created perpetual motion, and further more it couldn't possibly spin forever as the magnetic charge would eventually run out
What are you talking about? The spinning disc creates electricity and that is slowing down the rotation of that disc. Where do you see a perpetual motion?
It’s people like you who give others a chance for them and a reason for them to try new undiscovered stuff.... very cool!☺️👍
7:25 So it's actually communicating with every other object in the universe...
Me spinning around in my office chair: "I am transmitting myself to the universe!"
My coworkers: "Umm..."
Practically we can measure the "communication" we call that measure heat.
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.
I like how you explain the science behind your test.
Yeah it helps understand and learn about what's happening! ;D
yes if you didn't know it already.
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.
@@SeattlePioneer yes this is the correct explanation. What he says is completely wrong. I've found this to be the case with so many of his videos. They're just cool to look at but he mostly gets the science wrong.
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 ?
Mihai-Andrei Caţan I think it eventualy will tilt due to earth rotation.
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.
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.
Santeri Siiranen it has everything to do with friction. Friction comes in many forms and sources.
Cameron Dufton yeah it does but in this case it has nothing to do with slowing down the gyro
I always tought that banggood was a porn site lmao
Get your mind out of the gutter .
"Nothing spins forever."
Earth: uh oh
No the Earth eventually will stop. However ATOMS do.
@@blochebady2460 yes
Right! That's exactly what I was going to say. In fact, the Earth's rotation is slowing down.
Someone slap an alternator on it
@@OAlem Stop spitting random "facts"
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.
super interesting, thanks for commenting with this
This is the correct answer. Also, the initial spinning was quite lousy.
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.
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.
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?
it'll stop for 2 reasons, no perfect vacuum & cutting through magnetic flux takes energy (think of eddy currents when dropping a magnet through a copper tube)
You get 15 points out of 100. Those are not the reasons why the magnet stops spinning.
SedoKai love you how make a statement and treat it as facts without providing any facts to support your statement.. why are you on a science channel?
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.
No, it will stop for ONE reason: I fast-forwarded the video and watched the end first. It stops at the end. Therefore, back at the beginning, it WILL stop.
EvilPlagueDoctor i will stop because everything stops
I often fancied getting one of those levitating globes if it's a proper detailed globe, preferably illuminated somehow & maybe with a moon option. I imagine if you owned any of these levitating gadgets about 400 plus years ago you'd be put on trial for witchcraft! So cool!

Haha brilliant comment. If you put the words "fidget spinner" in anything it'll generate views.
Chaos theory, the small imperfections at the beginning will be aplified during the run, and destabilize it until it tips over cause of them?
I have now heard your explanation...and I think it's wrong, I challeng you to remove the magnet support, and leave it with just the 2 bear magnets, starting the spin already in vacuum using a remote controlled motor (powered via a super capacitor) joined with a chassis capable of stabilize the magnet already in midair! 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! Just the wabblings will make it tip over!
Remove the magnet support and leave only the magnet, uh? Man you are missing some physics lessons
I like this channel because I have a tendency to space off, so him explaining everything 3 times in a row is very convenient
The Action Lab try one of those sound levitating toys where sound holds an object suspended in the air. would this provide that sound waves are actually pressure.
No such thing as a perfect vac.
Secondly, vertices axis changes must surely absorb energy and slow the gyro quite quickly?
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.
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.
i agree, even in space there are gasses
The magnetic field loses its magnetism over time that's is also an important key to other perpetual motion devices
space
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! 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! Vibration is every machines enemy.
I assume then that you have viewed my YoiTube videos? If so, what do you think of them?

Now that's the explanation or comment I expected from people
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.
I’m pretty sure there are also tidal forces happening between the two. The deformation must be pretty minimal, but it’s still going to cause some locking eventually.
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
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).
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
those two responses sum it up well! well done!
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.
Wolf Edmunds not insignificant
Enough to slow it down
Omg he does start off every video with “ok”
Very cool to try stuff that people don’t.... you get props bro
The spinning top also induces eddy currents in nearby conductors, slowing the top down.
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
you can, in space
@Swifterr people cant make observations?
@@DyqnoDynamite what if even in space it will stop eventually it just will take millions of years because i'm pretty sure even in space theres still air that could generate friction or something like that
@@TactfulWaggle well Earth has been spinning for billions of years. given that the universe existed only for some billion odd years, i'd say it's pretty close to what people actually mean by the word "infinite"
@@igvc1876 if it spins the duration of your own life time. It cant be proven to you that it ever stopped..
I think Eddy current can slow it down, instead of moving the large magnet.
to let it spin way longer would it help fixing the lower magnet plus giving it a mechanic spin (something precice with power) ? i was thinking of more spin equals a higher zentipital force (the ones pulling rotating mass to the center) plus there "shouldnt" be a wabbeling of the lower plate if you lets say glue it to the desk or am i totally wrong ?

Wow now i feel wierd
Mr. Wolf it’s a song lmao
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.
I'm wondering if this is a problem for spin-stabilised satellites. I like the approach, experiment and then theorise.
A few years ago i randomly thought if it was possible to have something spin forever in a perfect vacuum chamber but i couldnt find any videos on it
Same here. I had this same toy. Asked myself the same question. Then I wondered if magnetic friction is a thing
and i belive that suppost to be in some space and not on earth
“Looks pretty stable”
*wobbling all over the place*
Question about levitation that you may be able to test. If I have a box that has magnetic levitation capability sides put that box inside of another box that is slightly larger that also has magnetic lifting capabilities on all sides on the inside.... This way the box in the center will be levitating no matter what you do... 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?
My friend spin it out side the device on a piece of plain glass, lift it a bit higher and land it slowly over magnet and when it comes near just shift the glass faster down and pull out side you will get the difference. Thanks for video.❤️

My phantom Orion only spins for eight minutes.😩😤
Do you really think *you* can top it?😂😂😂
I think if the top spins really fast, it's actually not stable! Something goes wrong, and it either precesses to a tilted angle and falls onto the base, or it wiggles itself sideways out of the floating-zone and falls to the table far away.
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.

Yeah I'm gonna have to disagree, induced eddy currents are probably the major reason it's slowing down.
Nice trick. Spinning forever is cool.

Dissident Undead exactly
yes a question how much longer did it spin in a vacuum? aprox. twice or?
Have you tried spinning it faster once it has started levitating by gently introducing a small air line like an air duster to it?
I think it will stop. Even though there is very little air resistance it will gradually lose it's momentum until it can't spin anymore

Nice video. I always watch and love your videos. Pointing out the obvious improvement that would be nice... paint a mark on the side of the gyroscope and use your camera frame rate to measure the speed and graph the rate of deceleration. Also, it would have been nice to use a high-speed motor to start the thing.
One of these spinning-magnet videos said that heat builds up in the magnets, hence a loss of rotational energy.
It will stop due to resistance caused by induced eddy currents
*edgy
Johnny Joestar would like to prove you wrong.
Hi
got a video idea! what about can this big magnet make this flying that gymoscope?
What if you try this with a gyroscope that levitates through a different mechanism like subzero temperature material and stuff
So technically a wireless friction prevents it from spinning forever. Cool.
Yeah, magnetic fields
Only seems wireless because you cant see the field. Its just as real as anything else and causes friction.

You must have a perfect vacume you can't do it you need a stronger vacume but eventually it will stop because the magnets are producing. Some resistance they are not perfect to the field
Is there such a thing?
"The actual density of hydrogen as it exist in interstellar space is on the average of about 1 atom per cubic centimeter. In the extremes, as low as 0.1 atom per cubic centimeter has been found in the space between the spiral arms and as high as 1000 atoms per cubic centimeter are known to exist near the galactic core."
hypertextbook.com/facts/2000/DaWeiCai.shtml
You cant make a perfect vacuum due to quantum fluctuations.
I believe the main reason is that a moving conductive object moving in a magnetic field induces current that discard energy. All other loss of energy causes you are talking are right, but negligible in front of the induced current.
Great video
1:19 They aren't opposite poles. They are the same poles.
there are still molecules in the vacuum causing friction
This isn't a perfect vacuum. There's no such thing in the real world.

did i happen to say MINIMUM
EVEN if there were ZERO atoms in a PERFECT vacuum,,, there is STUFF in the vacuum.. its called energy... you can measure this with a thermometer and with other devices..
this STUFF/energy affects any thing in the vacuum..its that simple.. newtons laws are theoretical since they can never be perfectly proven
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.
Is there any electrical current being induced in the metal of the magnet? Wouldn't that current dissipate heat (Joule heating) and cause the top to stop?
I think it’ll stop spinning from all the uneven movement and wobbling around it’s doing while hovering. Then again I’m not a science guy and that’s why I watch these interesting videos. Love the content btw ❤️
FULL VACUUM, MAGNETIC FIELD, SPININING EARTH, etc ...... I can not stop laughing 😂😂😂😂😂😂😂
wooow I'm getting one of them for my cat !
hahaha naaa the magnet :)
What about eddy currents. Can you try an experiment with laminated magnet so that there is more resistance to eddy currents ? Then it should keep spinning longer. Or may be use the top with high electrical resistance. That also should keep it spinning longer.
The magnetic force that is helping it hover has some friction of some kind resisting it to spin. So it will stop eventually.
If it keeps spinning we are all stuck in cobb's dream!
It will definitely stop because you can’t have a perfect vacuum.
Nope, a perfect vaccum is non existance. Existance itself denies the possibility of an absolute vaccum.
Yes perfect vaccum exists in space
Not completely bro there are still atoms bouncing around although be it not too many
@@razorreef3757
Exactly, not even space is a true vaccum. Just the closest you can get. All of existance has something in it. Thus a pure vaccum requires non-existance.
@@blankblank1284 How do you know far out into space where nothing exist isnt a perfect vaccum? Out somewhere far out in space i believe there is a perfect vaccum.
That was fun and enlightening.🎉
Can you use a dremel to accelerate the gyroscope to a super high RPM? So it might spin longer.
*AND THAT’S BEYBLADE*
thats magc!

It seems to me that it falls because you are spinning it by hand. That makes it difficult to get it level and create a stable spin. I would suggest a mechanical spinning device for your next experiment with this. It seems to be where there is tje most room for variance.

Ok. Suppose the magnet in the base was spinning same direction at same rpm(or close to). That would eliminate magnetic field friction. For that matter, even with atmospheric pressure, the top should spin indefinetly. Unless the airs friction is greater than the magnetic fields friction. But in the vacuum, it wont be.
Halifax Gibbet. With the base and top both spinning the top would lose the magnetic repulsion thus would not
"levitate".
It seems also we are forgetting the second law of thermodynamics: in a closed system entropy always increases.
@@timothystoutland6961
Hmm. I thought the magnetism and air friction would be eliminated because top and base have the same momentum
And the gyro would keep it balanced indefinely.
But it needs contrast in temperature in the immediate atmosphere to work? That's wild.
And I thought I was on to something. Rats.
I don't think that's true. It might lose spin-stability, but it would keep repelling magnetically until to top tipped over.
Hey. I loved your educational video. especially when you touched on "back ground radiation" which in my opinion has been misunderstood. My question is - Did I understand you correctly. Did you say that (back ground radiation) can cause a system to slow down?
Would the spinner spin forever if you use power to spin the magnet inside the box? Or would it just sync up its rotation with the momentum of the magnet inside the box and then collapse?
Earth gravity still works in you're vacuum and you have magnetic friction as well. spin it in space away from planets and you might be surprised of the result

Best investment hes ever made lol
He has made plants communicate bent light and checked concentrationof cyanide in apple seeds some few to mention
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.
Hello action lab! Isn't there any role of magnetic hysteresis in stopping that spinning top?
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.
Perpetual motion machines are impossible cause Einstein proved that energy can’t be created or destroyed and to make one there has to be electricity moving it.
no one said it would be perpetual motion
also he can turn the vacuum off once it reaches the pressure he wants
Fuck thermodynamics right
Always fucks us over but its life
Anyone else reading this like me would probably be like
‘I totally know what this means!’ (100* sarcasm in voice)
There is something called a "Valve" to maintain the vaccum after the desired pressure is reached, ever heard of it?
put a coil and diodes so they glow
on this disk
since magnet flux induction can give it enough electricity to glow a diodes bulb or led
Super cool music.sounds like soundtrack from how it's made
Would it spin for longer if you used a bayblade-esk release mechanism
