A superconducting magnetic energy storage system, including a superconducting persistent switch, is disclosed. The system includes a superconducting magnet connected in parallel with the persistent switch, both contained within a cryostat that is maintained at superconducting temperatures. Leads extending from the parallel connection of the magnet and switch are coupled to a power conditioning system, which in turn is coupled to a system load for which the system provides backup power. The disclosed persistent switch is fabricated as a wire having multiple superconducting strands within, and directly in contact with, an electrically conductive but non-superconducting stabilizer material. The persistent switch is normalized into a resistive state, to apply the stored energy to the load, by applying a rapid rise title current to the wire.
