PURPOSE:To provide a superconductive magnet apparatus which can suppress abnormal voltage generated in a superconductive coil to a lower value and also can prevent expansion of external leakage magnetic field even when a part of the superconductive coil shows dislocation to normal conduction state. CONSTITUTION:Each superconductive coil of first and second superconductive coil groups 10, 11 is divided into a plurality of layers in the thickness direction and the same layers of each layer are connected in series, coil protection elements 13a, 13b are connected in parallel with the coil group of the same layers connected in series and normal conductive dislocation generating members 12a to 12d which positively shows the normal conductive dislocation by generating the heat are provided at a part of the coil group of the same layer. |
