Explain the meaning of the word ‘ electromagnetic’ and ‘induction’ in the term electromagnetic induction. On what factors does the value of induced current produced in a circuit depend state on practical application of this phenomenon in everyday life.

Answer :

Electromagnetic: The word electromagnetic means the field produced by electrically charged objects. It involves the interaction between electrically charged particles.


Induction: The word induction means the process in which an electric or magnetic field is generated in the conductor when it is brought near an object with an electric field or changing magnetic field.


These two terms on combination form Electromagnetic Induction. It is defined as the production of electric current in the conductor when it is brought near the changing magnetic field.


In more simple terms electromagnetic induction can be explained as the process by which the change in the magnetic field in a conductor induces a current in another conductor.


Factors on which the value of induced current produced in a circuit depends are:


1. Nature of magnet: The value of induced current produced depends on the nature of magnet used. Greater the power of magnet, greater will be the induced current production.


2. A number of turns in a coil: More the number of turns in the coil, greater will be the amount of current produced. Suppose there are 10 turns in the coil, then the induced current produced is 10 times.


The practical application of electromagnetic induction in everyday life is Electric Generator.


It works on the principle of electromagnetic induction.
