The calculation of discharge current and magnetic pressure is essential in the analysis of an electromagnetic forming process. The finite element method is firstly used by the authors to calculate and simulate discharge currents and their results are regarded as the input in analyzing and simulating electromagnetic fields. The simulation results of discharge currents, the distribution of the magnetic induction and the magnetic pressure agree well with the virtually measured ones.
