More Information
Summary:A magnetic field generation device may include a coil generating a magnetic field, a drive part configured to apply a voltage to the coil or supply a current to the coil, a monitoring part configured to acquire state information whose value is varied together with temperature of the coil, and a control part which controls the voltage applied by the drive part or the current supplied by the drive part based on the state information acquired by the monitoring part.
