Emf(electromotive force) of the cell drives the current carriers to move in a specific direction.
This Emf causes positive and negative charges to flow in a specific direction. As a result current is generated.
Emf is a misnomer.
This means from the name it suggests it is a force but actually it is not.It is the potential difference between the two electrodes.
It is known as force because it acts as initial force to start the flow of charge.
Emf is defined as maximum work done per unit charge to take charge from one point to another.
It can be also defined as maximum potential difference between (+ive) and (-ive) electrodes of the cell in an open circuit.
Emf provides an energy which does the work to move the charge from one point to another.
As there is potential difference between the two electrodes the charges will flow.
