I have some bismuth metal, but it doesnt seem to repel from magnetic fields. So I was wondering if I need a stronger magnetic field or more bismuth, how can I calculate the diamagnetic force caused by bismuth? Any information would be a big help.
Answer 1:

The effect is too small, and the actual force calculation very complex.You will have better luck with graphite, which is also a diamagnet, and since it is much lighter, is more easily moved around using a magnet.You will need a very strong magnet of the kind found in large loudspeakers. Tell us if you need more information.
