Study of superconductors

Superconductivity is a phenomenon occurring in certain materials at extremely low temperatures, characterised by exactly zero electrical resistance and the exclusion of the interior magnetic field.

Superconductors are used to make some of the most powerful electromagnets known to man, including those used in Magnetic Resonance Imaging machines. They can also be used for magnetic separation, where weakly magnetic particles are extracted from a background of less or non-magnetic particles, as in the pigment industries.
