Emf attraction of thin-walled sheet metal

Abstract

The work is dedicated to EMF attraction processes which can deform both ferromagnetic and non-ferromagnetic sheet metal materials using low frequency discharges. The analytical models of both tooling configurations are based upon the solution of Maxwell equations in axially symmetrical formulation. The concept of attraction in this inductor system is based upon inducing currents flowing in the same directions in the screen and in the sheet metal blank.
