Vedclass · Answer

(A) magnetic needle acts as a magnetic dipole.In a non-uniform magnetic field,the magnetic force acting on the two poles of the needle will be different in both magnitude and direction.Because the magnetic field is non-uniform,the net force on the dipole is non-zero,resulting in a translational force.Additionally,because the forces on the two poles are not collinear and have different magnitudes,they create a net torque,causing the needle to rotate.Therefore,the magnetic needle experiences both a force and a torque.
