An apparatus and method for charging a superconductor, such as a high temperature superconductor (HTS), in-situ, including a superconductor that is magnetized by a magnet. A surface area of the magnet is smaller than a surface area of the superconductor and the magnet scans the surface area of the superconductor to magnetize the superconductor one portion at a time. An additional compression superconductor may be used to compress the magnetic flux from the magnet such that the magnetic flux exits the compression superconductor via an aperture on the surface of the compression superconductor and then impinges the surface of the superconductor being charged. The superconductor is assembled in a machine prior to being magnetized and may be cooled prior to magnetization.
