Abstract:

A large magnetic field is created in a hollow cylindrical superconducting ring by a method including the steps of A placing a snugly fitting cylinder of iron within the ring, B magnetizing the iron along its axis by means of a small applied field to its saturation induction, at a temperature above the transition temperature of superconducting ring material, C cooling the iron contained in the hollow cylindrical superconducting ring to below the transition temperature of the superconducting ring material, and D removing the applied field and the iron cylinder.
