Given: $N=100, I=1 \mathrm{~A}$, $\phi=2.5 	imes 10^{-5} \mathrm{~Wb} /$ turn Self-inductance of coil, $\begin{aligned} \mathrm{L} & =\frac{\mathrm{N} \phi}{\mathrm{I}} \ 	herefore \quad \mathrm{L} & =\frac{100 	imes 2.5 	imes 10^{-5}}{1}=2.5 	imes 10^{-3} \mathrm{H}=2.5 \mathrm{mH} \end{aligned}$ .
