This paper reviews the present state of development of high-field superconductivity with particular regard to the prospective use of that phenomenon in magnet coils for thermonuclear research. It is concluded that although magnets for thermonuclear research are not yet practical, their development is advancing rapidly to the stage of feasibility for that purpose. Progress at present is dependent upon the achievement of a greater understanding of the basic and applied science of superconductivity and the development of materials less susceptible to a phenomenon known as "flux jumping." A review of the present state of scientific knowledge pertinent to large-magnet technology is provided.
