Q. What is the coefficient of mutual inductance when the magnetic flux changes by $2 \times 10^{- 2}Wb$ and change in current in $0.01A$
A) $2\ henry$
B) $3\ henry$
C) $\frac{1}{2}henry$
D) Zero
Explanation
(a) $\mathrm{\Delta}\phi = L\Delta l \Rightarrow L = \frac{\Delta\phi}{\Delta I} = \frac{2 \times 10^{- 2}}{0.01} = 2H$
