Every magnet has two poles. Magnets found in nature are called natural magnets. Artificial magnets are made by people in laboratory.  Like poles of magnets repel each other and unlike poles attract each other.

A freely suspended magnet on the Earth's surface always points in the North-South direction. This suggests that the Earth itself behaves like a magnet which causes a freely suspended magnet to point always in north-south direction.

A magnet always has two poles: a north pole and a south pole. The poles of a magnet are represented in the figure below.

Cobalt, iron and nickel are attracted to a magnet. Hence, they are magnetic materials. Whereas, plastic can neither be magnetised nor it gets attracted to a magnet. Thus, it is a non-magnetic material.

Most of the pins stick at the two extreme ends of the bar magnet because the magnetic field is maximum at the ends of the magnet. The ends of the magnet where the strength of the magnet is highest are called the poles of a magnet.

A magnet has two poles: A North pole and a South pole. Like poles of magnets repel each other and unlike poles attract each other. A freely suspended magnet always points in the Earth's North-South direction.

Attraction can occur between unlike poles of two magnets as well as between a magnet and magnetic material. Therefore, the pieces that attract each other could be both magnets, or a magnet and a magnetic material. In case of magnets, repulsion occurs only between like poles. Therefore, repulsion is the most reliable test for magnetism.

One can transform an iron metal into a magnet by rubbing a magnet on the surface of the iron metal bar.
Position the magnet against the iron rod such that only the chosen pole is touching the rod. Begin at one end of the rod and rub the magnet down the length of the rod in one continuous movement.
Due to the rubbing of magnet, the magnetic domains in iron piece will be aligned in one direction, after which the iron bar will start behaving like a magnet.
This can be visualised by the diagram given below.

Magnetic materials are those materials which are attracted to a magnet. Magnetic materials are used to make permanent magnets. Copper is not a magnetic material. When placed near a magnet, copper is not attracted to the magnet. Hence, copper cannot be used to make a magnet.
