MHT CET 2026 Physics question

Torque acting on a coil carrying current 'I' situated parallel to magnetic field of induction 'B' having 'n' turns and area 'A' is

(A)
(B)Correct
(C)
(D)

Answer: (B)

Solution

The torque on a current-carrying coil is , where the magnetic moment is . Hence , option (B). When the plane of the coil is parallel to the field, the area vector is perpendicular to , so \vec{τ}$| =
