1. A method of manufacturing a planar coil construction for use in a force-producing device, comprising the steps of:

  • providing a first, sheet-like member defined by a first, continuous electrical conductor having a plurality of turns and first and second ends, the first end of the first conductor defining an electrical input and the second end of the first conductor defining an electrical output;

    providing a second, sheet-like member defined by a second, continuous electrical conductor having a plurality of turns and first and second ends, the first end of the second conductor defining an electrical input and the second end of the second conductor defining an electrical output;

    establishing an electrical connection between the second end of the first conductor and the first end of the second conductor;

    disposing the first and second sheet-like members parallel to each other with selecting turns of the first electrical conductor being positioned adjacent to selected turns of the second electrical conductor such that the direction of current flow through the turns of the first conductor is substantially in the same direction as the current flow through the turns of the second conductor, wherein the step of disposing the first and second sheet-like members parallel to each other is carried out by;

    providing first and second layers of two-sided tape, each layer being a size and shape to completely overlie the first and second sheet-like members;

    applying the first layer of two-sided tape to a selected side of the first sheet-like member;

    applying the second layer of two-sided tape to a selected side of the second sheet-like member;

    providing a layer of dielectric material; and

    attaching the exposed surfaces of the first and second layers of two-sided tape to the opposite sides of the layer of dielectric material.
