154778 A circular coil consists 70 closely wound turns and has a radius of $10 \mathrm{~cm}$. An externally produced magnetic field of magnitude $2 \times 10^{-3} \mathrm{~T}$ is applied perpendicular to the coil. The net flux through the coil is found to vanish when the current in the coil is $2.2 \mathrm{~A}$. The inductance of the coil is
