Abstract
A superconducting magnet device includes a main coil that generates a static magnetic field in an imaging space and a disturbance magnetic field compensation coil that suppresses influences of a variable magnetic field flowing inside from outside in the imaging space. The main coil is divided to at least two diode circuits. The disturbance magnetic field compensation coil has at least one coil formed of minus turns so that mutual inductances with the respective diode circuits in the main coil are made minimum.
