Superconducting magnet apparatus and control method thereof

摘要

Provided are a superconducting magnet apparatus with a switch that automatically connects or disconnects an external power source to a superconducting coil, and a method of controlling the same. The superconducting magnet apparatus includes a superconducting coil that generates a magnetic field when an electric current from an external power source is applied thereto, and a switch that supplies or shuts off an electric current output from the external power source by connecting or disconnecting the superconducting coil to the external power source.
