Report on VACE Experiments
Thomas E. Phipps
Force measurements by means of an analytic balance have been made to determine the interaction of two toroidal permanent magnets, of a type to which we have given the name ?Virtual Amp?rian Current Element? (VACE). We justify this name by showing that when kept at a fixed separation distance the toroids interact by the same law of angular dependence as Amp?re proposed for two ?current elements.?
