Will a Levitating Gyroscope Spin Forever in a Vacuum Chamber?

  • Added:  2 months 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!

    • Lucas alves da silva
      Lucas alves da silva 6 days ago

      The Action Lab I can be wrong but I think that gyroscopic procession only occurs when the gyroscopic force loses its strength to the friction so the gravitational force slowly pull the spinning object down this is the precession, so in my opinion if there's no friction the precession don't occur since the gyroscopic force will hold the gyroscope in the upright position....

      Well I'm not a physicist so I may be wrong, if so please correct me

      I don't think friction would come into it at all. Even if magnetic fields were shifting, when a field is formed it is a smooth curved field. It doesn't have any sticky spots like a surface. It is a just a nice smooth field. If the field weakened over time, then yes you called a reduction in magnetic domains. The rotation of the spinning body is what is keeping the top above the magnet fields, however there is some additional forces that are not in alignment with the opposing pole causing it to slow and MORE precession, more so than gravity alone.

      uh..you do know that slowing down means deceleration right?
      Acceleration and deceleration are on the same line / use the same measurement.
      So i guess, depending on your first question, it could be negative acceleration.
      Correct me if I am wrong.

  • Steven Ice
    Steven Ice 11 days ago

    Not sure how to tell in english but there is a so called friction loss which would lower the kinetic energy over time of the thing you're spinning. So in space for example it would spin for a very very long time (e. g. 1 billion years) but continuously losing it's spin impulse since theres no perfect vacuum in this universe - lol.

    It's similar to the Earth-Moon system. The tidal forces exerted by the moon were enough to increase the Earth's rotation period 3 times since the Moon first formed.

    it will stop... there are many other forces ... like the magnets in it and under it, the Earth's gravity, the Moon's gravity, too...the Earth's rotation, the Earth's magnetic field, and if even we ignore all of this, it still won't be spinning forever, couse there isn't such thing as full vacuum... even in the space there are few particles in every 1cm² soo it will resist it and eventually sometime will stop

  • Mario Duran
    Mario Duran 15 days ago

    I think that it will stop because of the imperfections in the initial spin and delayed decompression that will intervene with the conservation of angular momentum. If the initial spin where to increase in speed, with a well balanced motion and the vacuum being applied fast enough, it could have a chance of spinning for ever.

    I wont spin forever because of simple physics. When the top is spinning it is using kinetic energy, this kinetic energy is slowly running out. Sure air resistance is a factor to why is slows, but its not the only reason.

  • Sirmudkip III

    its gonna stop because even without air its in the middle of 2 conflicting forces (gravity and the levitation) it would have to be in inter galactic space for it to continue to spin indefinitely

    thanks for posting. some thoughts. i would guess, this toy makes use of something like a halbach array of neo-magnets in the base and a ring magnet in the spinner. as others have commented, there are several obvious factors that might increase slowing.
    if i had one of these, i would remake the spinner, with a lower center of mass and weighted rim, and make a 'launcher' to get it spinning. cheers

  • arnastu buttwehak
    arnastu buttwehak 28 days ago

    I think it'll stop because work is being done in the bobbing motion of the top, so energy is coming out of the system. Necessarily, this must come out of the spin.

    Ok, after the explanation, I don't entirely believe you. "There is still friction because the bottom magnet is moving" isn't convincing. I think the spin is bleeding off as a tiny induction current. But I wouldn't assert that with a high confidence level.

  • Xptechmike nosehairextractorguy

    The earth is also rotating which puts a stress on the axial plane and with each microsecond of stress there is a magnetic resistance. Other than that, there may still be quite a bit of air inside the box that your meter is not indicating.

  • Alessandro Porcelli
    Alessandro Porcelli 29 days ago

    A rotating object with axial simmetry (any sphere or ellipsoid or cylinder or whatever) won't radiate gravitational waves, also the CBR of all things is not that big of a problem, as it comes from every direction with the same intensity it won't actually make a difference. Of course you'd still have other effects which will make things problematic, such as the interaction with other bodies gravitational field introducing precession of the axis of rotation.

    4:31 it will stop because of induced current both in the spinning thing and in the base. Because of movements (side to side and that linear motion) of the thing and because of not even distribution of the field the thing has - thus rotating itself will induce currents.

  • Teren Essex
    Teren Essex Month ago

    it would stop because you can never pull a full vacuum. Even Nasa can't pull a complete vacuum with current technology. So it may spin for a very, very long time, but it would eventually hit enough air particles to slow it down enough

    I think it will stop because 2 things. First Tax. In thermodynamics. Can't remember which rule. But in all things theirs a tax on the energy used. The inertia used is being drained by itself, the magnets and even the gravity of the planet. Yes an object in motion stays in motion unless acted upon by an external force. And here there are more forces in play than just air.
