Abstract:
A superconducting magnet apparatus comprising: a cooling container for cooling contents thereof to a superconducting state; static-magnetic-field generating means, disposed in said cooling container and including at least one superconducting composite element having a superconducting composite structure serving as a holding medium for holding an electric current therein, for generating a magnetic flux in a predetermined uniform magnetic field region along a central axis thereof; and holding means for holding said static-magnetic-field generating means in said cooling container; wherein said at least one superconducting composite element provided with a temperature regulating device proximate thereto for heating said at least one superconducting element to control the temperature thereof, wherein said static-magnetic-field generating means is magnetized by induction-magnetizing, and wherein the magnetization value of said static-magnetic-field generating means is adjusted by controlling the temperature of said at least one superconducting composite element by means of said temperature regulating device.
