SUPERCONDUCTING COIL AND SUPERCONDUCTING DEVICE

Title:

SUPERCONDUCTING COIL AND SUPERCONDUCTING DEVICE

Document Type and Number:

WIPO Patent Application WO/2013/031679

Kind Code:

A1

Abstract:

Provided is a superconducting coil and a superconducting device in which loss can be reduced. A superconducting coil (10) comprises inner peripheral coils (12a, 12b) which are coil main bodies around which superconducting wires (15) are wound, and a first magnetic body (13) which is a magnetic circuit member. The magnetic circuit member is disposed so as to face the upper surface of the inner peripheral coil (12a) positioned on an end surface side intersecting the main surface of the superconducting wires (15) in inner peripheral coils (12a, 12b), and is composed of a magnetic body. The first magnetic body (13) is used to construct a magnetic circuit for enabling a magnetic flux generated by electric current flowing through the coil main bodies to circle the periphery of the electric current.
