In order to study the effect law of coil structure parameters to uniform distribution of mag- netic force in electromagnetic sheet forming, the 3D finite element models for electromagnetic field analysis were established by software ANSYS. The structure parameters on the distribution uniformity of the magnetic pressure were analyzed. The method of improving the e
