Will a Levitating Gyroscope Spin Forever in a Vacuum Chamber?

  • Added:  9 days ago
  • 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!

      well said nindjako.. there already is a force, besides gravity trying to tip it over. well noticed.. i think you are the FIRST to mention it...
      there are other objects that will always float above the magnets.. find one of those and see how long it spins. it will stop too.. maybe it will spin longer..
      now this is science.. trial ad error

    • Nindjako
      Nindjako 2 days ago

      I would like to add something - in the start of the video you pointed out that the gyro wants to tip over due to the magnets inside trying to align in the same direction (also gravity). Next you said that the gyro wants to keep it's rotational plane. The two forces counteract each other ( plus the starting angle ) making it wobble - this makes the gyro lose energy trying to stay stable, effectively slowing it down, the wobble increasing and finally tip over and fall

      Sorry if you or somebody else pointed that out already.
      Good job and have fun.

      I believe that it would stop no matter what you try because all matter is composed of multiple atoms with not completely stable boned and there for from the spin itself they are pulled apart and together using energy from the spin.

    I think it will stop in a vacuum because there is magnetic "friction".

    riddle me this.. what do you call a mass that falls and accelerates as it falls...
    sounds like gravity eh..
    its everything in the universe fallling from the center in all directions,, accelerating to terminal velocities.. in all directions outward..
    toward something of greater gravity.. answers every physics problem of any and every kind for 10,00 years.. answers every version of wrong , and revised math and physics for 10,000 years..
    everything is falling towards the gravity mass of the hands of GOD

  • RavenLuni

    Guess: It will undergo precession due to the field not being perfectly symmetrical and eventually a 'tipping point' will be reached

    It's also basically impossible to create a complete vacuum so there would still be slight air resistance. Even deep in space is not a full vacuum.

  • awesampwnah blahblLAH

    in addition to your explanation, say the top is spinning in space, outside of orbit, and is not affected by the gravity of anything around it. it would still stop spinning due to friction, as it is impossible to get a perfect vacuum (even in space), only an extremely un-dense space, as no matter what, trace residues will always be floating around

    If they would have used Bismuth it would have worked better because bismuth is opposite to both north and south magnetic poles so it hovers in mid air and doesn't flip.

    It'll still run out of spin and fall, the reason being that even in a vacuum it has drag to deal with - magnetic drag to be exact.

  • Kun Kodiik

    so if you could completely isolate something (no gravity or magnets or anything) it would spin forever.

  • Michiel Helvensteijn

    OK, I'll make a prediction having watched until 4:30. It will stop.

    First of all, I don't think air resistance was ever the main reason it would stop in the first place. It's a pretty aerodynamic design.

    Why will it stop? Well, it seems like a pretty unstable system. It's wobbling, and that will slow down a gyroscope.

    Would it stop in the theoretical scenario where the system was perfectly stable? I'm not sure. Eventually, I guess, by slow attrition of some kind or other.

    It's going to stop, because it's not air resistance that stops it but magnetic resistance, it may go a little longer but since it is already sleek and aerodynamic air isn't much of a factor.

    All so-called modern science is provably wrong. Stars are realtime. They can not be seen in space as you can not see primary light, it has to hit something first (or everything would be a fog, a very bright fog. Nothing moves, only consciousness - the Chinese knew this 5000 years ago. On and on, the real answers are out there, and make sense. Cool video by the way. If you spin the top in the right direction the spiral of incoming magnetism might keep it going by the way.

  • therealnightwriter
    therealnightwriter 4 days ago

    Gravity waves? What's that? They do not exist. You are right about the interconnectedness of everything. Here is what gravity is. There are exactly *2* people on youtube that will tell you this, a person ruder than me, and me. Just like the difference in light between a light bulb and a laser, gravity is the external magnetic push of the universe in the form of incoherent magnetism. (Incandescent bulb analogy) and a magnet is coherent magnetism, such as a laser is coherent light. The push of gravity is obviously blocked (not created) by mass, as the blocking effect of the moon means less pressure on the ocean beneath, high tide. Again, not a pull from the moon, but a blocking of the existing pull. So, the Sun blocks that push also, which since it radiates from a single source/point has the effect of blocking Earth with a slight wedge shape through the Earth. If something is spinning already, this will have the effect of keeping it going, but if not fast enough it will slow and lock, like the moon.

      I don't know why I respond to people like you...There is no problem proposing theories that oppose the current scientific consensus. In fact the goal of all real scientists wanting a break through is to prove the current theories to be incorrect. This is how science progresses. However, when new theories are proposed they have to agree with experimentation and other proven theories. The problem with everything you just said is that we can easily prove that it is false. We can show that all mass has gravity in a lab (this was done way back in the 1790s-Cavendish experiment), there are about 1,000 other experiments and just pure observation that easily show what you just said is complete nonsense. And the only comeback people like you usually give is that there is a massive conspiracy, that includes anybody that does an experiment that proves you wrong.

  • insidetrip101
    insidetrip101 4 days ago

    I'm not sure I would describe it as friction. It seems to me that there are three forces in this system: gravity; electromagnetism; and the initial kinetic energy required to make it spin. Gravity and electromagnetism are both two forces that are variable (i.e. their force applied on the object is dependent upon a variable, "t" for instance); however the kinetic energy is only applied at the initial spin and is therefore constant throughout.

    Now The issue here is that the constant force of the kinetic energy is worn away since the angular momentum of the gyroscope's spin is the true source of counteracting the gravitational force; i.e. the gyroscope "wants" to fall over because its in an unstable state being upright like that, but the angular momentum is fighting against gravity. Once gravity "wears away" at the angular momentum (each wobble decreases the momentum by a small bit) then the unstable upright position of the gyroscope collapses and it is no longer aligned with the magnetic force which gives its apparent levitation.

    No it won't spin 'forever', since the magnets will not last "forever" why?
    just a tip... getting rid of air does not get rid of gravity.

  • Charles-A Rovira

    It won't spin forever as the magnetic fields themselves cause drag. It's much less than atmospheric drag but it's still drag,

  • SaltyOwl

    It's gonna stop due to the magnetic resistance trying to tip it over. since its spinning it can stay up but it loses energy to keeping itself stable

    Interesting vid! Curious, have you ever tried spinning the the top on just the thin platform itself, then picking that up and slowly lowering it onto the Magnet base? Basically taking the magnet base out of the equation at first. Also I'm wondering instead of that thin platform if you could find a cheap convex spin station to get a really stable spin before releasing it on the magnet. Obviously that defeats the purpose of the $5 toy, but still curious if that would help make it last longer

    Again cool vid!

    yunonametaken 6 days ago

    Just FYI, an object with rotational symmetry spinning about it's axis does not give off gravitational waves. Nice video though! Also for an object spinning in space, I *think* that photons from the cosmic microwave background will exchange momentum asymmetrically depending on which side of the spinning object they hit. This would gradually slow it down, so even though gravitational waves won't do the trick, you're still right to say that it won't spin forever.

      +yunonametaken yes a lot of people have said this but any real object is not perfectly symmetrical and thus gives off gravity waves when spinning. For example neutron stars are pretty symmetrical but still give off gravity waves.

    plus even with zero atoms in the space, the top will inevitably stop spinning because it is experiencing magnetic resistance which causes wasted energy and the top will stop spinning. (follow the laws of thermodynamics)

  • chata lecheminant
    chata lecheminant 6 days ago

    the only way to acheive a full vacuum is in a locatoin inter galaxy where there is 1 atom per cubic meter. and in a vacuum on earth, it only reaches about 10-100 atoms per cubic centimeter. so obviously it will stop spinning, it will just take longer to stop.
