Vedclass · Answer

(B) According to the principle of reciprocity in mutual induction,the mutual inductance $M_{MN}$ is equal to $M_{NM}$.Given that the flux linked with coil $N$ due to current in coil $M$ is $\phi_{N} = M I_{M}$.Thus,$M = \frac{\phi_{N}}{I_{M}} = \frac{1.8 	imes 10^{-3} \ Wb}{2 \ A} = 0.9 	imes 10^{-3} \ H$.Now,for the flux linked with coil $M$ due to current in coil $N$,we use $\phi_{M} = M I_{N}$.Substituting the values,$\phi_{M} = (0.9 	imes 10^{-3} \ H) 	imes (3 \ A) = 2.7 	imes 10^{-3} \ Wb$.

There are $10$ turns in coil $M$ and $15$ turns in coil $N$. If a current of $2\ A$ is passed through coil $M$,then the flux linked with coil $N$ is $1.8 \times 10^{-3}\ Wb$. If a current of $3\ A$ is passed through coil $N$,then the flux linked with coil $M$ is:
