Abstract

An apparatus, a system and a method for wireless power transfer are disclosed. A method of forming a physical core of a wireless power transfer device includes positioning two or more electromagnetically permeable members adjacent to one another and applying longitudinal pressure to an end of the electromagnetically permeable members, the electromagnetically permeable members at least partially encapsulated in retaining compound. A wireless power transfer device includes a casing in which is housed an induction coil, a plurality of electromagnetically permeable members arranged in a line and a retaining compound.
