Hi! I have a question regarding the magnetic levitation formula. I calculated than the answer for (mu_0*p*g/x)in the formula b2/z=mu_0*p*g/x. It is 726.49 T2/m. I was wondering, that means that b2/z also has to equal 726.49 T2/m. Does that insure that the bismuth will levitate? In other words, if I calculate that (b2/z) is less than 726.49 T2/m, then the bismuth will not levitate? It has to be perfectly 726.49 T2/m... or more? Thanks for your help.
Answer 1:

Yes, that means that B2/z will also have to equal 726.49 T2/m. Anything greater than that should be when the Bismuth will levitate (keeping in mind that this equation is a simplification, and won't be exactly right).
