つた。 However, it can be easily analyzed that the magnetic field is relatively high at the axial end of the superconducting coil, and it is necessary to employ a fixing means for the connecting portion 4 that can withstand the electromagnetic force caused by this magnetic field. Furthermore, under a high magnetic field, the critical current value of the superconducting wire 3 of the connecting portion 4 generally decreases, and the resistivity of the protective base material also increases. For these reasons, conventional methods have had the disadvantage of causing deterioration of superconducting properties.
