Abstract：

Electromagnetic forming is a kind of advanced forming technology and its theory research related to (electromagnetics) and plasticity dynamics consists of the analysis of the magnetic pressure and the dynamic deformation analysis. In this paper, a dynamic measurement system of the magnetic induction intensity centered with digital oscilloscope is designed. The mathematical expression of the magnetic induction intensity can be obtained by curve fitting method. The equation shows that the magnetic induction intensity is a sinusoidal oscillation signal and its amplitude is a damped exponential law. It is important to verify the results of the theory research on the magnetic pressure and analyze the sheet deformation further.
