A square frame of side $\displaystyle 10$ cm and a long straight wire carrying current $\displaystyle 1$ A are in the plane of the paper. Starting from close to the wire, the frame moves towards the right with a constant speed of $\displaystyle 10 \mathrm{~ms}^{-1}$ (see figure). The e.m.f induced at the time the left arm of the frame is at $\displaystyle x=10 \mathrm{~cm}$ from the wire is :Official answer
(2)
$\displaystyle 1 \mu \mathrm{~V}$
