An inductive coil capable of providing power to the battery is described. The inductive coil is formed of a length of a wire having a conductive core capable of carrying an electrical current. The conductive core is surrounded by an insulating layer that electrically isolates the conductive core. Portions of the length of wire include a magnetically permeable material that is plated on an exposed surface of the conductive core.
