Abstract：

Forming coil is a key part to transform the electric energy into magnetic energy and to make the blank plasticdeformed during the electromagnetic forming.The principle of sheet metal electromagnetic forming was introduced,and the influence of the coil inductance to the forming efficiency,the distribution of electromagnetic force produced by some typical plane coils and the basic failure forms of coils were also analyzed.It is pointed out that in order to increase capacity usage ratio and coilse' life,its selection or design should be in accordance with the distribution and valuation of the forming force needed in sheet metal electromagnetic forming.
