Solution

EMF MMF
The electromotive force (EMF) is the force that causes electrons or current to flow in a closed circuit. MMF, or magnetomotive force, is the name given to this force which is produced as current flows through the conductor coil.
It is defined as the driving force that causes electrons in an electrical circuit to move around. It is defined as the driving force that causes magnetic flux to form in a magnetic field.
The amount of effort necessary to separate the charge carriers in a source current such that the force acting on the charges at the source's terminals is not a direct result of the field is referred to as the EMF. The development of emf is caused by internal resistance. The potential difference between any two locations in a circuit is bigger than the EMF. When current flows through a conductor coil, a force known as magnetomotive force or MMF is created, which drives magnetic lines of flux. In a nutshell, it is the driving force that causes magnetic flux to form in a magnetic circuit.
The SI unit of EMF is volts. Ampere is the unit of measurement for force.
