The generation of thrust vectors related to the algebraic sum of the first derivatives with respect to time of the electric current rise and fall slopes, acting upon a massive slab of copper has been described. The author is indebted to Dr. David King and Prof. Costas. Xydeas of the University of Manchester for many helpful discussions. John H. Schnurer for testing thrust generation and numerous discussions and to Dr. Anthony Leung for his suggestions. A2 Fig.1 Sketch of the experimental assembly.
