ABSTRACT:
The superconducting magnet apparatus includes a cryostat, a superconducting coil provided in the cryostat, and a current lead having a portion made of an oxide superconductor, for supplying a current to the superconducting coil. The portion of the current lead which is made of the oxide superconductor has a high-temperature end and a low-temperature end, and the current lead is arranged such that the direction of a current flow in at least the high-temperature end and the direction of a leakage magnetic flux applied from the superconducting coil to the high-temperature end are made substantially in parallel to each other.
