A superconductor is a material that loses its electric resistance when cooled below a characteristic temperature called the critical temperature. Many elements, alloys and compounds are superconductors. This state of zero resistivity is called the superconducting state. A superconductor has not only this property but also perfect diamagnetism. That is, when a magnetic flux density is applied to a superconductor, the interior magnetic flux density is zero:
