Abstract
A review of those aspects of superconductivity that are relevant to its use in the generation of high magnetic fields. The differences between the so-called hard and soft superconductors are outlined and the behaviour of hard superconductors in high magnetic fields is explained in terms of the formation of a mixed state. The filamentary and negative surface energy models that lead to such a mixed state are described. The use of hard superconductors in the form of wire or strip for the winding of solenoids is discussed. Attention is also given to the magnetization of superconducting rings by inductive methods. The future prospects for superconducting magnets are summarized.
