What is meant by induction?
Faraday's law of induction is to do with a change in magnetic fieldinducing voltage in a wire.
A change in magnetic field around any wire will cause a potentialdifference across said wire. Generators use perfectly coiled wireand permanent earth magnets to induce voltage into the coils whenthe shaft is turning.
Generators can be used backwards as motors if voltage is applied tothe coil rather than force applied to the shaft.
