ABSTRACT:
The present invention is intended to provide a magnet apparatus obviating the necessity of shield coils designed to suppress eddy currents. The magnet apparatus has gradient coils disposed in a bore of a cylindrical superconducting magnet, and includes a cylindrical structure that is realized with a combination of tiles made of a high-permeability material and that is interposed between the internal surface of the superconducting magnet and the external surface of the gradient coils. The tiles made of a high-permeability material are laminates made of a high-permeability material. The high-permeability material is a silicon steel plate or an amorphous magnetic material.
