Abstract :
The physical and the mathematical meaning of the equivalent magnetizing current method is clarified. It is proved that the method is the same as the method of Maxwell stress for the total force, but different for local force computation. Different computational procedures are analyzed. Another procedure is proposed, which makes it possible to compute either the total or the local force with an improved accuracy
