Abstract: A method and system for providing wireless power transfer through a metal object is provided. In one aspect, an apparatus for wirelessly receiving power via a magnetic field is provided. The apparatus includes a metal cover including an inner portion and an outer portion. The outer portion is configured to form a loop around the inner portion of the metal cover. The outer portion is configured to inductively couple power via the magnetic field. The apparatus includes a receive circuit electrically coupled to the outer portion and configured to receive a current from the outer portion generated in response to the magnetic field. The receive circuit is configured to charge or power a load based on the current.
