The effects on the superconductivity market of developments in magnetic resonance imaging and so-called high-temperature superconductors are reviewed, with applications of interest to electrical power engineers. The history of the subject is traced from its discovery in 1911, and values of critical temperature and field are tabulated for the principal superconducting materials of types I and II, with critical temperatures for seven ceramic compounds. Applications of intense magnetic fields in biomedical imaging, superconducting machines, levitation, separation, high-energy particle physics and nuclear fusion are considered. Energy storage and transport, lightweight power transformers, and microelectronic applications (Josephson junction voltage standards, logic devices and SQUIDs) are also covered.
