Patent ID: 8847721

Claim:
A thermally conductive electromagnetic coil, the coil comprising: a first coil layer comprising windings of a first wire, the first wire including a conductor and an insulator electrically insulating windings of the conductor within the first coil layer, wherein the windings of the first wire define outer first and second surfaces of the first coil layer, and wherein the insulator of the first wire is at least partially absent along the first surface of the first coil layer; and a second coil layer comprising windings of a second wire, the second wire including a conductor and an insulator electrically insulating windings of the conductor within the second coil layer, wherein the windings of the second wire define outer first and second surfaces of the second coil layer, wherein the first and second coil layers are positioned with the second surface of the second coil layer facing the first surface of the first coil layer, and wherein the insulator of the second wire is at least partially absent along the second surface of the second coil layer.
