TLDR
In this article, the magnetic shielding has been investigated by measuring magnetic coupling between primary and secondary coils separated by a high-Tc superconductor, which can explain the existence of superconductivity related surface current, which flows out from front to rear surface to couple with the secondary coil.Abstract:
The magnetic shielding has been investigated by measuring magnetic coupling between primary and secondary coils separated by a high-Tc superconductor. The magnetic coupling between primary and secondary coils could not be zero below Tc. This can be explained by the existence of superconductivity related surface current, which flows out from front to rear surface to couple with the secondary coil.read more
