Detailed explanation-1: -Types of Inductions: There are two types of Induction process: (1) Mutual Induction and (2) Self Induction.
Detailed explanation-2: -When a magnet is moved into a coil of wire, changing the magnetic field and magnetic flux through the coil, a voltage will be generated in the coil according to Faraday’s Law. In the example shown below, when the magnet is moved into the coil the galvanometer deflects to the left in response to the increasing field.
Detailed explanation-3: -Electromagnetic induction is the process by which a changing magnetic field in a conductor induces a current in another conductor. Two ways by which electric conductors can be induced in a coil are:i By moving the coil in a magnetic field. ii By changing the magnetic field around the coil.
Detailed explanation-4: -By increasing the rate of change of magnetic flux associated with the coil. By increasing the number of turns of the coil. The strength of the induced current can also be increased by altering the speed of relative motion between the coil and the magnetic field.
