A plane loop, shaped as two squares of sides \( a=1 \mathrm{~m} \) and \( b=0.4 \mathrm{~m} \) is introduced into a uniform magnetic
\( \mathrm{P} \) field \( \perp \) to the plane of loop. The magnetic field varies as \( B=10^{-3} \sin (100 \mathrm{t}) \mathrm{T} \). The amplitude of the current
W induced in the loop if its resistance per unit length is \( r=5 \mathrm{~m} \Omega \mathrm{m}^{-1} \) is
(1) \( 2 \mathrm{~A} \)
(2) \( 3 \mathrm{~A} \)
(3) \( 4 \mathrm{~A} \)
(4) \( 5 \mathrm{~A} \)
