Electromagnetic forming (EMF) is a high velocity forming technique that uses electromagnetic forces to shape metallic workpieces. In this work we present a numerical model that is able to compute the current flowing trough the coil, the Lorentz force acting on the workpiece and the optimum capacitance of the EMF process. The main advantage of our approach is that it provides an explicit relation between the capacitance of the capacitor bank and the frequency of the discharge, which is a key parameter in the design of an electromagnetic forming system. This method is computationally efficient because it only requires solving the time-harmonic Maxwell equations for a few frequencies to have completely characterized the EMF system. The approach can be very useful for estimating the order of magnitude of some parameters, for experimentation on modeling conditions, for coil design or for modeling complex geometries. Moreover, it can be easily included in a sequential coupling strategy without the worry of numerical instabilities.
