摘要：

Large persistent currents can flow in superconductors when they exhibit a large pinning force. The electromagnetic interaction between such persistent currents and magnetic field produces both repulsive and attractive forces. Various applications are now under consideration using such interactions. These include magnetic bearings, flywheels and transport systems. The pinned superconductor can also either shield or trap magnetic fields by persistent currents. Magnetic shield devices and superconducting permanent magnets can be made using such properties.
