A mutual inductor consists of two coils X and Y as shown in figure in which one quarter of the magnetic flux produced by X links with Y, giving a mutual inductance M. What will be the mutual inductance when Y is used as the primary?

The mutual inductance M remains the same whether X or Y is used as the primary.

Q. A mutual inductor consists of two coils $X$ and $Y$ as shown in figure in which one quarter of the magnetic flux produced by $X$ links with $Y$ , giving a mutual inductance $M$ . What will be the mutual inductance when $Y$ is used as the primary?

$M /4$

$M /2$

$M$

$2 M$

The mutual inductance $M$ remains the same whether $X$ or $Y$ is used as the primary.
