Title:
SYSTEMS AND METHODS FOR ACTIVATION OF TRAPPED FIELD MAGNETS
Document Type and Number:
WIPO Patent Application WO/2015/156883
Kind Code:
A3
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.
