The electric generator works on the principle that when a conductor is moved in a magnetic field then the current is induced in the conductor or in other words electricity can be generated by rotating a coil inside magnetic field.
The electric generator is a machine for producing electric current or electricity. The electric generator convert mechanical energy into electrical energy.
Principle of working of an electric generator:
Electric generator is an application of electromagnetic induction.
Electric generator works on the principle that when a straight conductor is moved in a magnetic field, then current is induced in the conductor
In an electric generator a rectangular coil is made to rotate rapidly in the magnetic field between the poles of a horseshoe type magnet. When the coil rotates it cut the magnetic field lines due to which current is produced in the coil .
Electric generators are of two types:
Alternating current generator(A.C generator)
Direct current generator (D.C generator)
