Abstract
An object of the present invention is to provide a persistent current switch with high heating efficiency by simplifying the configuration of the persistent current switch and reducing the heat capacity. To achieve the object, a superconducting magnet in accordance with the present invention includes a superconducting coil, a persistent current switch, and one of an alternating-current power supply, a pulsed power supply, or a charge/discharge circuit. The one of the alternating-current power supply, the pulsed power supply, or the charge/discharge circuit is connected to a loop circuit of the superconducting coil and the persistent current switch such that it is in parallel with the persistent current switch.
