A circular loop of area \( 1 \mathrm{~cm}^{2} \), carrying a current of 10
\( \mathrm{P} \) \( \mathrm{A} \), is placed in a magnetic field of \( 0.1 \mathrm{~T} \) perpendicular

W to the plane of the loop. The torque on the loop due to the magnetic field is
(1) zero
(2) \( 10^{-4} \mathrm{Nm} \)
(3) \( 10^{-2} \mathrm{Nm} \)
(4) \( 1 \mathrm{Nm} \)
