A square loop of wire, side length \( 10 \mathrm{~cm} \) is placed at angle of \( 45^{\circ} \) with a magnetic field that changes
\( \mathrm{P} \)
uniformly from \( 0.1 \mathrm{~T} \) to zero in \( 0.7 \mathrm{~s} \). The induced
W
current in the loop (its resistance is \( 1 \Omega \) ) is
(1) \( 1.0 \mathrm{~mA} \)
(2) \( 2.5 \mathrm{~mA} \)
(3) \( 3.5 \mathrm{~mA} \)
(4) \( 4.0 \mathrm{~mA} \)
