Magnet:- Those materials which have attractive and directive properties.

Two types of magnet:

2. Artificial magnet: The magnet which is stronger than natural magnet and have desired shape such as

1. Bar magnet
2. Magnetic needle
3. Horse shoe magnet
4. Ball ended  magnet

Properties of the magnet:

1. Attractive properties: A magnet attract small pieces of iron, nickel, cobalt etc. When brought near the heap of iron fillings, the ends of the magnet shows greatest attraction called poles of the magnet.
2. Directive properties: When a magnet is suspended or pivoted freely, it aligns itself in the geographical north-south direction called north and south pole of the magnet respectively.
3. Like poles repel and unlike pole attract each other.
4. Magnetic poles always exist in pair.
5. Magnetic monopoles do not exist.
6. A magnet induces magnetism in a magnetic substance placed near it. This phenomenon is called magnetic induction.
