PROBLEM TO BE SOLVED: To reduce overloads acting on the inside even when a current in a superconducting coil fluctuates with time relating to a superconducting magnet apparatus and a nuclear magnetic resonance imaging apparatus to which it is applied. SOLUTION: Magnetization members (21, 22) disposed coaxially with the center axis (Z) of the superconducting coil and magnetized by a static magnetic field induced by a permanent current are provided with slits (21f, 22f) having openings from opposite surfaces (21b, 22b) to side peripheral surfaces (21a, 22a).
