* A number of magnets with North Pole and South pole marked on it.
Take 2 magnets and let the north pole of one magnet face the north pole of another magnet. Observe what happens. Next take 2 magnets and let the north pole of one magnet face the south pole of another magnet. Observe what happens and note it down. Repeat the 2 procedures a number of times and note down your observations.
Like poles repel each other, unlike poles attract each other.
* The north pole of one magnet will not attract the north pole of another magnet and will push it away. Hence like poles do not attract each other. * The south pole of one magnet will attract the north pole of another magnet and vice-versa. Hence unlike poles attract each other.
