Hi gang, Some time ago there was a lot of traffic about diamagnetic materials. Bismuth is the strongest known. This is avail. at www.unitednuclear.com (I don't own any of their stock.) 1/4 lb is $6 and 1 lb is $20. I read somewhere that if you cast a bar of Bi and suspend it by a string, it will point east-west. I haven't tried it.
