Answer to Question 1

Answer: Faraday's law states that voltage induced in a coil is proportional to the rate at which the magnetic field strength through the coil changes. It is also proportional to the number of turns on the coil. This change can be brought about by moving the coil, changing its shape, or changing the magnetic field strength. Because of Faraday's law, the production of current need not be restricted to batteries, but can be induced in a wire by any of the changes stated. Faraday's law underlies generators and has changed the electrical and industrial world.

Answer to Question 2

Answer: Both electric motors and generators are similarly-constructed devices. Both have a permanent or electromagnet and coils of wire on a rotor. They differ mainly by the roles of input and output. When input is electrical energy, the rotor is made to spin and we have a motor. When input is mechanical energy that spins the rotor, the output is electric energy and we have a generator.
