Abstract：The assumption that a multi-turn coil equivalent to the metal plate was in series was proposed firstly, and then an electromagnetic coupling double coils model was established which reduced complexity of the ERM solution. Secondly, parameters of the model were obtained thinking of the ERM as two coaxial circle coils with a rectangular section. The time domain iteration algorithm was employed to realize the ERM simulation lastly. The comparisons between test and simulation demonstrated rationality of the assumption and correctness of the simulation algorithm, and the simulation error was within 5%.
