Question

Please explain the principle and working of Electric Motor and Generator separately in brief.
Please cooperate, tomorrow is my science exam.

Answer 1

working of this are not coming and principle of electric generator uses the movement of a rectangular coil of wires between the poles of a horshshpe magnet to produce an electric current. and that of motor works on the principle that even a rectangular coil is place in a magnetic field and current is passed through it, a force act on a coil and rotates it

Answer 2

There are two types of generators, one is ac generator and other is DC generator. Whatever may be the types of generators, it always converts mechanical power to electrical power. An AC generator produces alternating power. A DC generator produces direct power. Both of these generators produce electrical power, based on same fundamental principle of Faraday's law of electromagnetic induction. According to this law, when a conductor moves in a magnetic field it cuts magnetic lines of force, due to which an emf is induced in the conductor. The magnitude of this induced emf depends upon the rate of change of flux (magnetic line force) linkage with the conductor. This emf will cause a current to flow if the conductor circuit is closed.Hence the most basic tow essential parts of a generator are

1. a magnetic field

2. conductors which move inside that magnetic field.

Now we will go through working principle of DC generator. As, the working principle of ac generator is not in scope of our discussion in this section.
