Abstract：

In electromagnetic forming, the shape and dimension of the working coil directly affect the force acting on the parts, thus affect the forming results of the parts. In this thesis, the distribution of the force acting on the part when an elliptic working coil is used is given through the formula deduction and numerical calculation, and it is validated by experiments. By comparison with round coil, the conclusion about when an elliptic coil can used is got.
