A strong magnetic field generator, which comprises a vacuum vessel and a plurality of superconductive coils wound on the outer periphery of the vacuum vessel. It also comprises a plurality of protective coils wound on the vacuum vessel and a control means functioning, upon occurrence of quenching in at least one of the superconductive coils, to reduce current in the superconductive coil with quenching therein for removing the quenching while at the same time causing current corresponding to the reduction of current in the superconductive coil with quenching therein to flow through the protective coils.
