A method for making a multilayer toroidal field coil free from the bending moment is studied by applying File's theory to each layer of the coil. According to this method, the shape of a multilayer toroidal field coil is determined so that the layers in the winding are in pure tension and, therefore, are not subject to any bending moment. The winding thickness of the resultant coil is not uniform along the winding. Successive layers are no longer in contact, leaving some empty space between them. Tension on a conductor varies in magnitude from layer to layer and is constant in the same layer, as in a solenoidal coil. A toroidal field coil with a magnetomotive force of 18.8 MA T, a vertical bore of 1.51 m, and a horizontal bore of 1.07 m is designed with this method.
