<p><P>PROBLEM TO BE SOLVED: To efficiently exhibit characteristics of a superconductive coil by preventing a critical current from being decreased by reducing a vertical component to the tape surface of a superconducting wire in magnetic fields applied to the superconducting wire at both end positions in the axial direction of the superconductive coil when a magnetic field is generated among a plurality of superconductive coils. <P>SOLUTION: In the superconductive magnet device 10, the superconductive coil 30 around which the superconducting wire 30a formed of a tape is wound is disposed oppositely with a space 50 in a vertical direction X with respect to a tape surface, and magnetic flux is generated between ends in an axial direction Y of the superconducting coil 30. In the superconductive magnet device, a magnetic field shielding plate for preventing the magnetic flux from being short-circuited is arranged between the tape surfaces by magnetic field components generated in the vertical direction X with respect to the tape surfaces at the space 50 between the tape surfaces that oppose the superconductive coil 30. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
