Electromagnetic sheet metal forming (EMF) is a high‐speed forming process driven by the dynamics of a coupled electromagneticmechanical system. The purpose of the current work is the investigation of a possible reduction in the yield stress due to electric currents. While thermoelastic and viscoplastic effects are well‐understood, the possible influence of electric currents on dislocation motion, generally referred to as the electro‐plastic effect [3], is still an unresolved issue.
