Why does a compass needle get deflected?
Compass needle get deflected when brought near magnet due to the force of the magnet.
The lines along which the iron fillings align themselves represent magnetic lines of force.
Magnetic field is a quantity that has both magnitude and direction. The direction of the magnetic field is taken to be the direction in which a north pole of the compass needle moves inside it.
The field lines emerge from the north pole and merge at the south pole out side magnet
.Inside the magnet, the direction of field lines is from its south pole to its north pole. Thus the magnetic field lines are closed curves. This is why no two field-lines are found to cross each other.
