Given figure shows the north and south poles of a permanent magnet in which an ‘n’ turn coil of cross-sectional area ‘A ’ is resting, such that, when a current ‘I’ is passed through the coil, the plane of the coil makes an angle ‘\theta’ with respect to direction of magnetic field ‘B ’. If the plane of magnetic field and the coil are horizontal and vertical respectively, the torque on the coil will be

None of the above since the magnetic field is radial

Given figure shows the north and south poles of a permanent magnet in which an ‘n’ turn coil of cross-sectional area ‘A’ is resting, such that, when a current ‘I’ is passed through the coil, the plane of the coil makes an angle ‘θ’ with respect to direction of magnetic field ‘B’. If the plane of magnetic field and the coil are horizontal and vertical respectively, the torque on the coil will be

nIAB cos‌θ
nIAB sin‌θ
nIAB
None of the above since the magnetic field is radial
