Abstract
A system for activating trapped field magnets in a superconducting material may include a superconducting material element and an electromagnet source disposed proximate the superconducting material element. The electromagnet source may be configured to produce a magnetic field pulse sufficient to activate the superconducting material element. The superconducting material element may be configured to retain a trapped magnetic field that is substantially equal to a magnetic field generated by the magnetic field pulse.
