Meissner effect The falling off of the magnetic flux within a superconductor when it is cooled to a temperature below the critical temperature in a magnetic field. It was discovered by Walter Meissner (1882-1974) in 1933 when he observed that the Earth's magnetic field was expelled from the interior of tin crystals below 3.72 K.
