Magnetic shield
First Claim
1. An ICPT system including a transmitting coil and a receiving coil wherein at least one coil is at least partly shielded by a magnetic shield formed of one or more conductors wherein the shield has a surface which in use is exposed to an incident magnetic field wherein the one or more conductors undulate towards and away from the surface so as to distribute currents induced in portions of the one or more conductors at the surface of the shield to portions of the one or more conductors away from the surface of the shield.

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.
