Abstract
A superconducting magnet device includes a superconducting coil, a quenching protection circuit that is connected in parallel to the superconducting coil and that allows a current in one direction, and an excitation power supply that is connected to the superconducting coil with proper polarity determined such that a current flows in the one direction to the quenching protection circuit when quenching occurs in the superconducting coil, and excites the superconducting coil. The excitation power supply is configured to detect incorrect connection with the superconducting coil when the excitation power supply is connected to the superconducting coil with a polarity opposite to the proper polarity.
