What is the Meissner Effect

The Meissner effect is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state, discovered by German physicists Walther Meissner and Robert Ochsenfeld in 1933. They discovered it by measuring the magnetic field outside superconducting tin and lead.

Some materials tend to expel a magnetic field, materials that do this are called diamagnetic, but the effects of this diamagnetism are weak. For example, water and the human body are diamagnetic materials.

In superconducting material the Meissner effect creates currents which completely oppose the magnetic field applied by a magnet, in other words they will repel a magnet. This consequently makes a superconductor in the Meissner state a perfect diamagnet.
