Re: "Faraday's Disk" which started it all

OK, Bill,

My scope beam is much too fast moving compared to the spin of the fridge
magnet.

How about hanging a pair of charged pith balls on threads above the spinner?
We can use some plastic wrap to avoid wind effects.

Now do you think the balls will move depending on the direction and speed
of spin?
