High temperature superconductor magnetic-switch |
摘要 |
A magnetic switch for recording the change in position of a magnetic field includes a first object on which is positioned a source of magnetic force for creating a magnetic field and a second object on which is positioned at least one type II superconducting medium. The type II superconducting medium exhibits a permanent magnetic component after exposure to a magnetic field, such that relative motion between the first object and the second object causes the magnetic field to induce a residual magnetization in the superconducting medium. A device for sensing the direction of a magnetic field includes a first type II superconducting medium adapted to exhibit a permanent magnetic component after exposure to a magnetic field having a first direction, a second type II superconducting medium adapted to exhibit a permanent magnetic component after exposure to a magnetic field having a second direction orthogonal to the first direction, and a third type II superconducting medium adapted to exhibit a permanent magnetic component after exposure to a magnetic field having a third direction orthogonal to the first and second directions.
