Solution

EMF MMF
1. It is term as electromotive force. 1. It is term as magnetomotive force.
2. It is the force required to move an electron in an electric circuit. 2. It is the force required for creating magnetic flux in a magnetic circuit.
3. It is measured in $v o l t s$ . 3. It is measured in $a m p e r e - t u r n s$
4. It is the amount of work done to carry a unit charge from one end to another end of the wire. 4. It is the product of the current and number of turns.
Mathematically, $E = \frac{W}{Q}$ where, $W$ is the work done
$Q$ is the charge
Mathematically, $F = N I$
where $I$ is current and $N$ is the number of turns.
