Abstract
Abstract A coil form for supporting coils of wire includes three intersecting orthogonal plates whose peripheral surfaces together define an imaginary spherical surface. The plate peripheries increase the effective winding area of the coils with respect to the exterior dimensions of the coil form. Terminal posts for the ends of the coil wires are positioned on the plates so as not to waste space and not to project beyond the imaginary sphere.
