摘要：

A three-dimensional calculation method for magneto-dynamics with moving objects has been developed. Its features are as follows: (1) An IEM approach, based on the integral expression of magnetic vector potential, is applied to calculate eddy current, magnetization and magnetic force. (2) Transient current in coils can be calculated by considering motion of the coils or magnetic substances. (3) An external circuit including a condenser, resistance or electric source can be considered. The method has been applied to the evaluation of dynamic characteristics of linear type voice coil motor and calculation results agreed well with experimental data.
