A circular loop of area \( 1 \mathrm{~cm}^{2} \), carrying a current of \( 10 \mathrm{~A} \), is placed in a magnetic field of \( 0.1 \mathrm{~T} \) perpendicular to the plane of the loop. The torque on the loop due to the magnetic field is
\( \mathrm{P} \)
(A) zero
(B) \( 10^{-4} \mathrm{~N}-\mathrm{m} \)
(C) \( 10^{-2} \mathrm{~N}-\mathrm{m} \)
(D) \( 1 \mathrm{~N}-\mathrm{m} \)
