ABSTRACT:
Methods of fabricating electromagnet assemblies are disclosed. In one embodiment, a includes forming a first helix and a second helix, each helix having a first end and a second end and a substantially oval cross-section, the cross-section having a major axis, each helix being configured to concentrate electromagnetic flux at a midpoint on the major axis. Each helix is bent at an angle and offset from the major axis, resulting in a first planar surface including the major axis and a second planar surface. The first and second helixes are oriented such that the outer edges of the respective second planar surfaces coincide and the outer edges of the respective first planar surfaces are in diametric opposition. The first and second helixes are affixed by their respective second planar surfaces, and electrically connected by their respective second ends.
