Magnets do have a lot of utility in our lives. It has a lot of use of it in factories and decreases human effort by a huge margin. Magnets are the gift of nature which help our civilization to develop and reach new heights.
Types of Magnets
There are two types of magnets:
- NATURAL MAGNETS: These magnets are available in nature. Example: Magnetite, Hematite and many any iron-containing rocks.
- ARTIFICIAL MAGNETS: These magnets are not available in nature and made artificially by human beings. Example: Bar magnet, Horse-shoe magnet and the ball ended magnet.

Poles of a Magnet
Suppose we keep many magnetic materials near a magnet. We will observe that most of the iron filings will be attracted towards the two ends of a bar magnet. These ends are addressed as the poles of the magnet. Then we can try and bring a few magnets of different shapes and check for the location of the poles on these magnets with the iron filings.
Properties of Magnets
- Magnets have two poles- the North Pole and the South Pole. The magnetic substances are more attracted to the poles than the other parts of the magnet.
- We can get the directions of the compass with the help of the magnet.
- When we hang a magnet freely, its South Pole is always towards the Earth’s North Pole.
- We can make a magnet by rubbing it against a magnet.
- We can even make a magnet by putting an iron bar’s side near the poles of the magnet.
- We can even make a magnet by passing electricity through an iron bar.
Recap
- There are two types of magnets-natural and artificial.
- Natural magnets are those magnets which are available in nature.
- Artificial Magnets are those magnets which are made by human beings.
- Magnets have two poles- the North Pole and the South Pole. The magnetic substances are more attracted to the poles than the other parts of the magnet.
