1. :
- A superconducting magnet comprising;
a coil unit formed of an oxide superconducting wire having a surface in a form of a strip and wound;
a residual magnetic field restraint unit formed of a magnetic substance, disposed in said coil unit, and having a throughhole extending in an axial direction of said coil unit, andthe residual magnetic field restraint unit has a length in the axial direction larger than a length of the coil unit in the axial direction,wherein said residual magnetic field restraint unit includes a pipe having a wall thickness equal to or larger than 1 mm; and
wherein said residual magnetic field restraint unit configures a portion of a container that accommodates said coil unit therein.

Abstract
A coil unit (10) is formed of an oxide superconducting wire having a surface in a form of a strip and wound. A residual magnetic field restraint unit (81) is disposed in the coil unit (10). The residual magnetic field restraint unit (81) has a throughhole (HL) extending in an axial direction (Aa) of the coil unit (10). The residual magnetic field restraint unit (81) is formed of a magnetic substance. A residual magnetic field can thus be restrained.
