He cooled Mercury and found that all its electrical resistance went away. Electricity in a superconducting wire will continue to flow virtually forever with no added energy. Superconductors also expel magnetic fields. So if you put a magnet over a superconductor, the magnet will levitate. How is this possible? Quantum m
