Abstract
A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method includes forming a structure comprising layers of material extending along a first aperture path. The structure includes multiple concentric layer surfaces. A channel is formed in each of the layers of the material and along each of the multiple surfaces. Conductive material is positioned in each channel to provide a spiral configuration. The surfaces of multiple ones of the layers are of tubular shape. The layers of material are sequentially positioned one over another and about an axis along which first and second opposing coil end regions are formed. The layers are formed with a region of a first thickness and a shoulder region. The shoulder region is alternately formed in the sequence at one coil end region or at the other coil end region. Each shoulder region has a greater thickness than the first thickness.
