In this paper, the influence of permeability on flux density in magnetic circuits is relegated to a minor importance. Here, permeability is considered as a mere measure of the effectiveness of amperian currents in increasing magnetic intensity. Based on this interpretation, the solution of problems related to magnetic circuits excited by permanent-magnets is reduced to the solution of problems related to magnetic circuits excited exclusively by energized coils
