Magnetic levitation - superconductors

  1. Oct 27, 2015 #1
    The question I have is rather simple and straightforward so here it is: How much weight can a magnet support and still levitate above a superconductor?

    We all know about super fast levitating trains and I want to use the same idea for something else. However before looking deeper into magnetic levitation and starting a research I would like to make sure it is actually even possible.

    So putting a permanent magnet above a superconductor:
    - does it barely levitate or
    - could it hold ##1000m## and still levitate if ##m## is the mass of the magnet?

    I am not looking for an analytic solution. Just a rough guess or a link to some article would be good enough at the moment! Basically the whole idea is that I want to lift (for a couple of mm would suffice) an object using a levitation. The levitation has to be stable.

    Thanks for all the help!

    That's not unrealistic.

    This paper could have numbers.
