Q:
Using a superconductor i would be able to levitate a magnet. now keeping it stable then moving it to another area is my problem. Is it possible? I need help because this is my project transportation of goods using magnets realizing vision 2016 in Botswana

A:
Yes, with superconductors (unlike ordinary permanent magnets) stable levitation is possible. The magnet may sit at an elevated spot above, for example, a ring of superconductor. If you move the superconductor in a very steady way, without much acceleration, the magnet should move along with it. For real practical applications, used in some fast trains, more elaborate arrangements are needed.
