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