Hey guys I was wondering what would happen if: took a ball neo magnet, balanced it on a few other magnets to basically make it a frictionless bearing. Then spin the ball magnet to 10k rpm. But do all this in a box thats a vacuum. Would the neo ball magnet spin basically for a VERY long time since there is no or very little friction since it probably wouldn't be a 100% vacuum? What if you could make the box be 100% vacuum, would it spin forever?
