The figure below shows the north and south poles of a permanent magnet in which n turn coil of area of crosssection 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 
. If the plane of the magnetic field and the coil are horizontal and vertical respectively, the torque on the coil will be
A
B
C
D
None of the above, since the magnetic field is radial
Text Solution
Verified by ExpertsThe correct answer is:
A
Plane of coil is having angle 
with the magnetic field.
