The substances that attract objects made of steel, iron, nickel, and cobalt are called magnets. Iron, steel, or alloys of iron are the substances used to make magnets. The magnets form by the process of magnetization.
The magnets occur in different shapes and sizes. The different types are rectangular magnets, cylindrical magnets, horseshoe magnets, U-shaped magnets, ring magnets, and button magnets.
Magnetic materials are those which get attracted by a magnet. Some examples are iron, cobalt, or things made with these substances.
Materials which do not get attracted by magnets are called non-magnetic materials. Some examples are: paper, pieces of cloth, eraser, wood.
Every magnet has two ends which are known as the north and south poles. The poles of a magnet have more power to attract objects.
The letter N represents the north pole, and the letter S denotes the south pole.
The same type of poles are called poles, and an example is a south and south pole. When the poles are different, we call them unlike poles. An example is- the North pole and the south pole.
The different poles attract each other, and the like poles repel each other.
