MAGNET MAGNETIZING SYSTEM AND SUPERCONDUCTING MAGNET TO BE MAGNETIZED

Title:

MAGNET MAGNETIZING SYSTEM AND SUPERCONDUCTING MAGNET TO BE MAGNETIZED

Document Type and Number:

Japanese Patent JP2009170565

Kind Code:

A

Abstract:

To provide a magnetizing system for a superconducting bulk magnet that can shorten the length of a bulk superconducting magnet using a magnetizing method in a magnetizing static magnetic field to downsize the bulk superconducting magnet as well as a small-sized bulk superconducting magnet magnetized by this magnetizing system.

A magnetizing magnetic field generating means is made up with a magnetizing superconducting bulk magnet, building another magnetizing bulk superconductor therein, a bulk superconductor to be magnetized before magnetization thereof is inserted within a space of the static magnetic field, which is generated by the magnetizing superconducting bulk magnet magnetized, and after the magnetized bulk superconductor is cooled down to a superconducting temperature or below after insertion by a cooling means, the magnetic field of the magnetizing superconducting bulk magnet is eliminated, thereby magnetizing the bulk superconductor to be magnetized.
