Claim:
1. An electrical device configured to wirelessly transmit or wirelessly receive power as part of a wireless power transfer system, the electrical device comprising: a ferromagnetic material comprising at least one orifice; at least one electrical conduit extending through the at least one orifice of the ferromagnetic material from a first region on a first side of the ferromagnetic material to a second region on a second side of the ferromagnetic material, the second side opposite to the first side, the at least one electrical conduit configured to have at least one alternating current flowing along the at least one electrical conduit between the first region and the second region, the ferromagnetic material and the at least one electrical conduit configured to reduce power loss within the ferromagnetic material caused by a circumferential magnetic flux generated within the ferromagnetic material by the at least one alternating current, wherein the at least one orifice interrupts the generated circumferential magnetic flux in the ferromagnetic material by the at least one alternating current flowing along the at least one electrical conduit.
