Define MMF and state its unit.

Description : Define MMF and state its unit.

Last Answer : M.M.F. stands for magnetomotive force. M.M.F. is the force behind the flow of magnetic flux. MMF is defined as the force behind the flow of magnetic flux or production of magnetic flux is called as ... ampere and unit for number of turns is turns. So the unit for M.M.F. is ampere turns.
