Stephen,
I respectfully disagree with your analysis. The rotation of the ball
comes from friction with the track as the ball is attracted by the magnet.
No friction, the ball would just slide along the track. The magnet doesn't
have anything to do with the angular momentum directly.
But, isn't Stephen saying that [angular] momentum is simply transferred to the Earth?
Hey, if we all jog from west to east real fast, can we make the day longer? ;-)
Yes, but only as long as you keep jogging. As soon as you stop the day
length goes back to what it was to start with.
