If the magnet doesn't hold the ball, then how does it pull the ball back up? Also when the magnet pulls the ball up the wheel should turn in the other direction.

You seem to have a variable strength magnet. How do you do that, use and electromagnet with a variable current applied? Anyway I didn't see the ball moving up and down in the video.

See gentle readers? Paul can't even come up with an answer that is consistent within 3 lines.
