Abstract
A superconducting device includes a coil formed of a superconducting wire, an iron core to which the coil is attached, and a magnetic material arranged in a magnetic circuit and magnetized by magnetic flux. The magnetic circuit is generated by energization of the coil and passes through the iron core. A gap is formed between the coil and the iron core, or/and a nonmagnetic material is interposed between the coil and the iron core.
