Answer» tic NEEDLE kept non-parallel to the magnetic FIELD in a non-uniform magnetic field EXPERIENCES (C) both a force and a torque.Explanation:The magnetic needle as North Pole and South Pole which acts as magnetic dipole.Since, it is placed in non-uniform magnetic field, then the forces acting at the two ends of the needle is different from each other. Thus, force is acting on the needle.From QUESTION, the field is not parallel. Thus, torque is acting on the needle.So, both torque and force is acting on the magnetic needle. |
