Abstract
In a high field superconducting magnet device, e.g., for NMR, a conventional low temperature superconducting solenoid type magnet is combined with an inserted superconducting magnet, which is fabricated from high temperature superconducting materials having very high critical currents. Both magnets operate with stability at the same low temperature in persistent modes after operating conditions are achieved. The flux field and superconducting currents in the inserted superconducting magnet are generated by flux trapping when the field of the low temperature superconducting solenoid type magnet is reduced. The field of the hybrid magnet assembly is the resultant of the respective fields of the two magnets.
