(54)Superconducting magnetiser


(57) A magnetizer (304) for magnetizing permanent magnets (308) positioned in-situ a mechanical member (302) is disclosed. The magnetizer comprises at least one primary superconducting coil configured to project a magnetic field flux configuration of a first type to at least a portion of a distal volume of a first type, and at least two auxiliary coils symmetrically disposed about the at least one primary superconducting coil and configured to project magnetic field flux configurations of a second type to at least a portion of a distal volume of a second type. A method (700) of magnetizing a permanent magnet in-situ within a mechanical member is also disclosed.
