PULSED ACTIVATION OF TRAPPED FIELD MAGNETS

摘要

A system for activating trapped field magnets in a superconducting material is disclosed. The system includes a superconducting material element and an electromagnet source disposed proximate the superconducting material element. The electromagnet source is configured to produce a magnetic field pulse sufficient to activate the superconducting material element. Furthermore, substantially all of a magnetic field generated by the magnetic field pulse is contained within an area that has smaller physical lateral dimensions than the superconducting material element.
