Superconductive MRI Systems

Superconductive MRI Systems use electromagnets made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation (e.g. with helium). In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can therefore produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings.
