Abstract
A method of producing electrical coils includes preparing a plurality of coil layers. Each coil layer is prepared by printing an electrically conductive coil pattern on a layer substrate. Each coil pattern includes an inner end at a first via through the substrate at a point radially inside the coil pattern, and an outer end at a second via through the substrate at a point radially outside the coil pattern. The method also includes joining the coil layers into a stack and electrically connecting successive coil patterns of the plurality of coil layers to one another through the vias to form a conductive coil extending through the stack.
