Electromagnetic Forming (EMF) is a promising and relatively new manufacturing technology having significant advantages over conventional forming processes. A primary characteristic of this process is use of noncontact electromagnetic forces to achieve forming and shaping  of various metal work pieces. Mechanically, this is a high-strain rate forming process. From the modeling and simulation perspective, it can be identified as a coupled multiphysics problem, involving circuits, electromagnetic fields and structural deformations. A basic requirement in modeling and  imulation of EMF processes is the computation of  orentz forces over the job piece as well as the coil. In the present work, modeling and computation of such  forces for a stranded coil and job piece geometry are reported. The results of simulation of this configuration and impulse excitations are presented. These are startup simulations related to a project on modeling and simulation of electromagnetic forming processes taken up at Indian Institute of Technology Delhi.
