Electromagnetic Forming by Distributed Forces in Magnetic and Nonmagnetic Materials
IEEE Transactions on Magnetics, 2004 In this paper, we discuss the electromechanical force densities associated with pulsed electromagnetic fields in inhomogeneous, linear media with conductive losses, in the context of a process of shaping metal objects. We show that the conductivity and the gradients in permittivity and in permeability lead to volume forces, while jump discontinuities ...
