(a) From $\phi = Mi$
$\frac{M_{1}}{M_{2}} = \frac{\phi_{1}}{\phi_{2}} = \frac{10^{- 3} 	imes 200}{0.8 	imes 10^{- 3} 	imes 400} = \frac{10}{16} = 0.625$

Q. Two coils $A\ and\ B$ have 200 and 400 turns respectively. A current of 1 A in coil A causes a flux per turn of $10^{- 3}$ Wb to link with $A$ and a flux per turn of 0.8$\times 10^{- 3}$ Wb through B. The ratio of mutual inductance of $A\ and\ B$ is
