Space applications of superconductivity: high field magnets

This is the second of a seven part series on the potential applications of superconductivity in space. A very general review of superconducting magnet technology is given, followed by a description of proposed magnet applications in space. The few programmes which actually flew magnets are also described. We conclude that many interesting possibilities exist for the future, but that their early realization will require a new direction for magnet research - toward very light, often very large structures with large amounts of stored energy.
