the magnetic repulsion force must be equal to the force due to gravity at a set distance
F = (Constant)(M1)(M2)/distance^2

the proper rationalization may contain magnetic skill density. The skill density in a magnetic field is B^2/2mu_0. Magnetic fields from distinct sources upload in a linear way, i.e. B_total=B_1+B_2. So the entire skill density contained in the magnetic field will be (B_1+B_2)^2/2mu_0 = (B_1^2 + B_2^2 + 2*B_1*B_2)/2mu_0. So in evaluation to the skill contained in the field of each and every magnet independently, one finally ends up with one better skill time period B_1*B_2/mu_0 even as both fields superimpose. In nature each and everything works in one of those way that actual equipment always attempt to diminish their entire skill. by technique of bringing both magnets together, we've made the field better and this bring about a higher entire skill. by using skill minimization function of structures, which means both magnets will journey forces which will push them aside till the added skill time period is 0, which may ensue on the magnets being at an unlimited distance. The closer they get, the better the overlap of both fields, the better the contribution of the mixed B1_*B_2 skill time period and the better the rigidity pushing them aside. in case you pick to appreciate allure, inspect what occurs with (B_1 - B_2)^2. right here the mixed skill time period has a detrimental signal and the perfect field is weakest even as the magnets are close together... subsequently they're going to attraction to. in reality issues are somewhat better complicated than that, nevertheless, because the magnetic field of each and every magnet will change the magnetization of the textile of the different magnet, in spite of the indisputable fact that the mandatory skill minimization argument remains an similar. it is only better complicated to calculate numerically. desire this facilitates.

Permanent magnets in the train are repelled by a magnetic field generated in coils in the track. This can provide locomotion as well as support.

what is wrong with the people at yahoo answers...haven't you guys ever heard of search engines or wikipedia.....oh wait..I get it
I guess its more easy to have someone else type a few alphabets and search and then paste the link here.....right?
