A method of manufacturing a coil assembly, comprising:
- acquiring a sheet of a conductive metal;
- producing a plurality of coils from the sheet of conductive metal;
- layering at least a first coil and a second coil of the plurality of coils with an insulation layer there between to construct the coil assembly,
- wherein the first coil is within a first layer of the coil assembly and is oriented in a first spiral direction,
- wherein the second coil is within a second layer of the coil assembly and is oriented in a second spiral direction that is opposite the first spiral direction;
- and
- electrically coupling the first and second coils within the coil assembly.
