The figure shows a square loop L of side $\displaystyle 5$ cm which is connected to a network of resistances. The whole setup is moving towards right with a constant speed of $\displaystyle 1 \mathrm{~cm} \mathrm{~s}^{-1}$. At some instant, a part of L is in a uniform magnetic field of $\displaystyle 1$ T, perpendicular to the plane of the loop. If the resistance of L is $\displaystyle 1.7 \Omega$, the current in the loop at that instant will be close to :
Official answer
(4)
$\displaystyle 170 \mu \mathrm{~A}$
