ABSTRACT:
A superconducting magnetic coil formed of anisotropic high temperature superconducting material includes ferromagnetic flanges positioned coaxial to the longitudinal axis of the coil and at the ends of the superconducting coil to capture magnetic flux emanating from the coil so that the maximum perpendicular magnetic field at the end regions is reduced. A reduction in the maximum perpendicular magnetic field increases the critical current at the end regions thereby increasing the critical current at these regions and maintaining an overall higher critical current of the coil.
