Question

mutually induction and self induction

Answer 1

the ans is When this emf is induced in the same circuit in which the current is changing this effect is called Self-induction, ( L ). However, when the emf is induced into an adjacent coil situated within the same magnetic field, the emf is said to be induced magnetically, inductively or by Mutual induction, symbol ( M ).

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 .
