Pure tension shape of a thick torus

This report discusses the forces on an ideal toroidal coil system. It is demonstrated that the total vertical force on the top half of both a thin-shell torus and a thick torus depends only on the inner and outer major radii at the midplane. The total vertical force is divided in half to find the pure tension magnitude from which the shape of the pure tension curve can then be determined. A convenient method of solution is presented with several example curves for different coil thicknesses
