Question

Explain the concept of self inductance and mutual inductance.

Answer 1

Hi mate.

Thanks for asking this question.

Here is your answer,


$self \: induction \:$

The phenomenon of the production of an induced e. m. f. in the coil, due to change in current in the same coil is known as self induction.

Consider a coil carrying a current (i) .
The magnetic Flux linked with the coil is directly proportional to current.

¢ = Li

Where L is the self induction.




$mutual \: i duction$

When two coils are comes near to each other and the current of coils are changed then, e.m.f. is induced in the nearer coil.
This phenomenon is known as mutual induction.

Answer 2

MUTUAL INDUCTION- consider two coils of wire kept side by side. When the strength or direction of the current in one coil changes the magnetic flux around it changes. As a result an emf is induced in the secondary coil . This phenomenon is the mutual induction.

SELF INDUCTION- The change in the magnetic flux due to the flow of an AC in a solenoid will generate a back emf in a direction opposite to that applied to it. This phenomenon is known as self induction .
