Abstract
A superconducting magnet which provides a barrier to current flow transverse to the length of the superconductor at operational temperature and voltages, while also providing a magnetic quench protection mechanism for the superconducting magnet. The superconducting magnet comprising a plurality of winding turns of superconductive material wound into a coil and a variable electrically resistive layer varying with either temperature or voltage positioned between at least of portion of the plurality of winding turns of the superconductive material, wherein the variable electrically resistive layer has a negative temperature coefficient of resistance or is a semiconductor with a threshold voltage greater than operational voltages.
