A rectangular loop \( (a \times b) \) carries a current \( i \). A uniform magnetic field \( \mathbf{B}=B_{0} \hat{\mathbf{i}} \) exists in space. Then,
\( \mathrm{P} \)
W.
(a) torque on the loop is \( i a b B_{0} \sin \theta \)
(b) torque on the loop is in negative \( Y \)-direction
(c) if allowed to move the loop turn so as to increase \( \theta \)
(d) if allowed to move the loop turn so as to decrease \( \theta \)
