Magnetic Shielding Using High-T sub c Superconductor

The magnetic shielding has been investigated by measuring the magnetic coupling between primary and secondary coils separated by a high-T sub c superconductor. The magnetic coupling between primary and secondary coils could not be zero below T sub c . This can be explained by the existence of superc...

Description
Summary:The magnetic shielding has been investigated by measuring the magnetic coupling between primary and secondary coils separated by a high-T sub c superconductor. The magnetic coupling between primary and secondary coils could not be zero below T sub c . This can be explained by the existence of superconductivity related surface current, which flows out from the front to the rear surface to couple with the secondary coil. 4 ref.--AA
