Comparison between Magnetic and Electrical Circuits

When we compare the Magnetic and Electrical circuits, M.M.F is analogous to E.M.F., flux to current and reluctance to resistance.

In electric circuit as per Ohm’s Law:

                             I = V / R

Similarly in magnetic circuit when Ohm’s Law is applied:

                           Magnetic flux = m.m.f / Reluctance

The laws of reluctance in series and parallel are the same as those for resistance in series and parallel.
