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.
