A solid-nitrogen cooled high-temperature superconducting magnet for use in magnetohydrodynamic marine propulsion

Abstract:

A small high-temperature superconducting (HTS) magnet has been produced as part of a magnetohydrodynamic (MHD) propulsion unit to power a model boat. The magnet is wound from 6 pancake coils of Bi-Sr-Ca-Cu-O HTS tape (BSCCO-2223), and is conduction cooled using an onboard "thermal battery", containing 3 liters of solid nitrogen. The magnet is racetrack shaped, and aluminum electrodes are placed along the straights of the magnet to pass an electric current through the saltwater, perpendicular ...
