Question

Define mutual inductance and write its S.I. units.

Answer 1

Define mutual inductance and write its S.I. unit.

(b) Derive an expression for the mutual inductance of two long co-axial solenoids of same length wound one over the other.

© In an experiment, two coils ${ c }{ 1 }$

and ${ c }{ 2 }$

are placed close to each other. Find out the expression for the emf induced the coil ${ c }{ 2 }$

due to a change in the current through the coil ${ c }{ 2 }$.

Answer 2

Mutual Inductance is the interaction of one coils magnetic field on another coil as it induces a voltage in the adjacent coil.

S.I. unit of mutual inductance is Henry.
