The principal reason voltage is
induced in the loops of a generator coil is that the loops are rotating,
changing the amount of magnetic field within the loops. The answer is letter A.
For example, in a circuit, the electrons in
the bulb will not move without the potential difference or voltage. When there
is voltage, electric current occurs because there is a driving force for the
electrons in the wire to move.
