Question

A square loop (L = 0.1 m for each side) is placed in a region of constant magnetic field (B = 0.1 T, to the right). The plane of the loop makes an angle of 30 degree with respect to horizontal as shown. A current (1 = 0.1 A) is flowing in the loop in the direction illustrated. What is true concerning the torque at the moment shown in the figure? (A) It is in the clockwise direction and is increasing (B) It is in the clockwise direction and is decreasing (C) It is in the counterclockwise direction and is increasing (D) It is in the counterclockwise direction and is decreasing

Explanation / Answer

torque T = BiAsintheta

it is rotasting in clock wise direction and decreasing torque
