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

A

`r=niABcostheta`

B

`r=niABsintheta`

C

`r=niAB`

D

None of the above, since the magnetic field is radial
