Superconductivity and magnetism

  1. Certain objects are able to influence the behavior of magnets when super-cooled. Does this violate Maxwells equations?

    The Meissner effect: http://en.wikipedia.org/wiki/Superconductivity#Meissner_effect

    Superconductivity is a quantum effect and is a property of materials.

    Maxwell's equations only describe the fields; material properties must be injected via auxiliary equations.
  4. I appreciate the quick response. What happens to the magnetic field of a super-cooled magnet?

    Magnetic substances don't become superconductors when cooled, or at least, they loose their ferromagnetic properties when transitioning into the superconductive regime.
