Fill the container about half full of water. Float a leaf on the surface of the water,
and float the needle on the leaf. That'll be a beautiful demonstration. I think I'll
make one, and I thank you for the idea.

I'm not sure, but I can tell you that I have a very cheap (97 cent) compass that suddenly started reading backwards. I fixed it by placing it directly on top of a magnetizer-demagnetizer for several seconds (like one you use to temporarily magnetize screwdrivers with) and now it reads normal again. *I only used that tool because that's the only real magnet that I have lying around. A regular magnet may have worked as well.
