In this paper, a new, general form of the equivalent magnetizing current method is proposed for calculating the total force of magnetized bodies in contact, including ferromagnetic and permanent magnet. This method is formulated in way similar to the generalized equivalent magnetic charge method. It provides consistent numerical results of force calculation, whether or not one magnetized body is in contact with the other one. The validity of this evaluation method for magnetic forces is shown by close observation of the formulae and numerical test results
