Abstract

A magnetic shield for shielding adjacent coils of an ICPT system. One or more conductors are configured to distribute induced eddy currents from the surface of the shield to below the surface and thus reduce heating due to eddy currents.The magnetic shield may be employed to transfer power over rotary couplings, such as the shaft of a wind turbine.
