Place the non-magnetic sphere on the top edge of the bow and let it fall.
When it reaches the bottom of the bowl, let it circle.
Do the same with the magnetic sphere and observe the difference in behavior.
The non-magnetic sphere rolls down the side of the bowl quickly and circles easily in the bottom of the bowl with only a quick movement to get it started.
On the other hand, the super magnet falls grudgingly and hardly makes a circle in the bottom of the bowl even when you move the bowl manually.
