Abstract

PURPOSE:To secure the quick attenuation for the coil current by using the material the resistance value of which is increased with the heating by the current flowing there to the protective resistance. CONSTITUTION:Protective resistance 3 is connected to superconductive coil 1 to consume the energy of the coil. In that case, resistance 3 increases its value with the heating by the current flowing there. As a result, the coil current can be attenuated quickly.
