発明の名称 (英語) SUPERCONDUCTING MAGNET AND NUCLEAR MAGNETIC RESONANCE DEVICE
発明の概要(英語)

Disclosed is a superconducting magnet in which uniformity of the central magnetic field is secured by eliminating magnetisation produced by the shielding current of the superconducting winding and thus making the current that is passed to the superconducting winding uniform. The super conducting magnet is provided with a superconducting winding (2) and an outside AC winding (4) constituted by a superconductor or non-superconductor that is wound coaxially with the superconducting winding (2), outside the layer of superconducting winding (2). Magnetisation is eliminated by applying an AC magnetic field in a direction perpendicular to the direction of magnetisation produced by the shielding current generated in the superconducting winding (2), by passing an AC current to the outside AC winding (4). Also, there is provided an inside AC winding (7) constituted by a superconductor or non-superconductor that is wound coaxially with the superconducting winding (2), inside the layer of superconducting winding (2). The current direction in which current is passed in the outside AC winding (4) and the current direction in which current is passed in the inside AC winding (7) are made to be in mutually opposite directions.
