( Electrical engineering : General )
The potential difference between two points of a conductor creates an electromotive force which pushes free electrons in a conducting material to move towards the positive
terminal, creating current.
This varying magnetic field induces a varying electromotive force or "voltage" in the secondary winding.
Electromotive force is voltage, or the difference in the electric tension or the difference in charge
between two points that causes an electric current.
