266429 A coil is suspended in a uniform magnetic field, with the plane of the coil parallel to the magnetic lnes of force. When a current is passed through the coil it starts oscillating it is very difficult to stop. But if an aluminium plate is placed near to the coil, stops. This is due to

1 Electromagnetic induction in the aluminium plate giving rise to electromagnetic damping
2 Development of air current when the plate is placed
3 Induction of electric charge on the plate
4 Shielding of magnetic lines of force as aluminium is a paramagnetic material
