A plane loop, shaped as two squares of sides a = 1 m and b = 0.4 m is introduced into a uniform magnetic field\[\bot \] to the plane of loop (figure). The magnetic field X. varies as\[B={{10}^{-3\,}}\sin \,(100t)\,T\]. The amplitude of the current induced (in A) in the loop if its resistance per unit length is \[r=5\,m\Omega {{m}^{-1}}\] is ________.
