Abstract

The present disclosure is generally directed towards magnetization of permanent magnets (14) using superconducting magnetizers. For example, in one embodiment, a superconducting magnetizer assembly (18) is provided. The assembly includes a coil pack having an inner coil (44) including a first superconducting magnet material, the coil being configured to generate a first magnetic field in response to an electric current supplied to the coil, and an outer coil (42) including a second superconducting magnet material, the outer coil (42) being disposed about the inner coil (44) and being configured to generate a second magnetic field in response to an electric current supplied to the outer coil (42). The coil pack also includes a container configured to house the inner and the outer coils (42,44).
