Vedclass · Answer

(B) In a moving coil galvanometer,a radial magnetic field is essential to ensure that the magnetic torque remains constant regardless of the coil's orientation. This is achieved by using concave (cylindrically cut) magnetic pole pieces and placing a soft iron core inside the coil. The concave shape of the pole pieces ensures that the magnetic field lines are always parallel to the plane of the coil for any angular position,making the field radial. Therefore,the correct option is $B$.
