If the operativeforce law were the Grassmann law, his claim would be valid. Thereis now ample experimental evidence available proving that, inselfcontained circuits, the reaction forces between parts of thecircuit are governed by Ampere's law and not by Grassmann' s. Twelveof these experiments are described in Graneau's book [P. Graneau,Ampere-Neumann electrodynamics of metals , Hadronic Press, NonantumMA, 1985].The Grassmann law fails precisely in the situations whichare being considered by Marinov. All experiments performed withmetallic conductors in the 165 years since Ampere formulated hislaw have been in agreement with this law.The Ampere law easily explains the various motoring actionsshown in this paper. The propulsion forces are reaction forcesbetween parts of the circuit which can move relative to each other.Consider figure 1. When ABC and FGH are stationary and slidingcontacts are provided at C and F, the bridge will move in thef3-direction, but the f3-forces are not acting on DE. They arelongitudinal forces in CD and FE produced by repulsion acrossthe corners from BC and GF.The same longitudinal forces also explain the rotationof the motor when BC and GF are metal discs with sliding contactsto CD and FE.The Ampere force law predicts that Marinov 's motor willnot rotate if C and F are welded conductor junctions and AB andGH are made very long compared to DE. The current from a batteryor other source would then have to be introduced with slippingcontacts at A and H. Also the battery leads would have to be keptwell away from the motor. If the motor still rotates withthese modifications, then I accept Marinov has proved his pointof selfpropulsion.
