Quantum Levitation

Levitation of a magnet above a cooled superconductor can been explained by the Meissner Effect. If a superconductor is cooled below its critical temperature while in a magnetic field, the magnetic field surrounds but does not penetrate the superconductor. The magnet induces currents in the superconductor which create a counter-magnetic force that causes the two materials to repel. The induced currents are due to the presence of the external field and not due to flux changes as frequently seen in metals (Faraday’s and Lenz’s laws)
