Abstract
Provided is a superconducting coil capable of reducing a magnetic field perpendicularly irradiated to a wide surface of a superconducting wire composing a coil of a superconducting electric device by winding a low current density coil, driven with a current density lower than that flowing through a main coil, on a line extending from the main coil. The superconducting coil includes: a main coil driven with a current density flowing by entering current; and a low current density coil located on a line extending from upper and lower ends of the main coil, and series connected to a coil having the same shape as a portion of the main coil to be driven with a current density lower than that flowing through the main coil.
