Answer:
It is defined as the ratio of magnetomotive force (mmf) to magnetic flux.
However, magnetic flux passing through a reluctance does not give rise to dissipation of heat as it does for current through a resistance.
Explanation:
Ohm's law for the magnetic circuit's states that the MMF is directly proportional to the magnetic flux hence as the magnetic flux decreases, the MMF also decreases.
