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.

A magnetic coil comprising: an anisotropic superconductor wound about a longitudinal axis of the coil, the coil generating a magnetic field that varies along the longitudinal axis, and a ferromagnetic member disposed proximally to and spaced from at least one end portion of the coil for reducing perpendicular magnetic field components of the magnetic field at the at least one end portion of the coil, wherein the ferromagnetic member has inner and outer radial portions radially disposed proximally and distally from said longitudinal axis, respectively, said inner and outer radial portions axially spaced from the at least one end portion of coil by first and second distances, said first distance greater than said second distance.
