Abstract
A superconductor bulk magnet magnetizing method providing a more homogenous trapped magnetic field includes: placing the bulk magnet inside a charger bore of an electrical charger magnet; placing a field correction unit inside a superconductor bore of the bulk magnet; applying an electrical current (I) to the charger magnet, to generate an externally applied magnetic field, wherein a temperature Tof the bulk magnet exceeds a bulk magnet critical temperature T; applying an auxiliary electrical current (I, . . . ) to the field correction unit, thus generating an auxiliary magnetic field applied to the bulk magnet from within the superconductor bore, wherein T>T; lowering Tbelow T; turning off the electrical current at the charger magnet, wherein T<T, and turning off the auxiliary electrical current at the field correction unit, wherein T<T; and removing the bulk magnet from the charger bore while T<T.
