Magnetic equivalent circuit with permanent magnets
Magnetic field strength, H is measured in ampere-turns per metre and to convert these to the equivalent of voltages in an electric circuit you multiply by the path length - OK this produces a quantity with the units of amperes (actually magneto motive force and equivalent to emf in e-circuits) and that might confuse the innocent but, it is strictly correct - why then do you consider bringing relutance into the equation as being relevant. (By the way it isn't).
