Abstract
A superconducting magnetic coil includes a first superconductor formed of an anisotropic superconducting material for providing a low-loss magnetic field characteristic for magnetic fields parallel to the longitudinal axis of the coil and a second superconductor having a low loss magnetic field characteristic for magnetic fields perpendicular to the longitudinal axis of the coil. The first superconductor has a normal state resistivity characteristic conducive for providing current limiting in the event that the superconducting magnetic coil is subjected to a current fault.
