A motive magnetic system includes a first coil configured to produce a constant magnetic field. The first coil includes a support structure having a groove and a high temperature superconductor (HTS) cable comprising a metal at least partially filling the HTS cable. The cable is disposed in the groove. A second coil is configured to produce an alternating magnetic field. The first coil and the second coil are positioned so that the constant magnetic field and the alternating magnetic field interact to cause a magnetic force between the first coil and the second coil that causes motion between the first and second coil.

The present invention provides a pinning center introduction device, a pinning center introduction method and a superconductor tape. The pinning center introduction device includes a bending shaft and a heating zone. The bending shaft is arranged in the heating zone. The superconductor tape is arranged around the bending shaft. The heating zone keeps the superconductor tape entering the heating zone and the bending shaft at a target temperature. The superconductor tape is bent on the bending shaft to obtain strain, so that a micro-structure of a superconducting film is reconstructed under the action of the strain and the target temperature.
