The main virtue in magnets is to attract iron objects. By placing it in such a way that it can rotate freely, one end of it stays in the north and one end in the south direction. Magnets are widely used in electronic devices. Different shaped magnets are used for different uses. Let's we discuss about the different shapes of magnet.

How to made Magnet?
A magnet is a piece of iron that attracts iron objects to itself. But it has magnetic force. Do you know how this power comes?
When an electric current flows, an electric field is formed around it. When iron is placed in this field, the iron atoms are arranged in a certain direction. And it becomes a magnet.
Magnets are made in 2 ways and there are 2 types.
A coil of metal wire wrapped around the iron and electricity is inserted into it to form a temporary magnet. A temporary magnet means magnetic force as long as it has an electric current.
By rubbing a large magnet in the same direction with another iron, a piece of iron becomes a magnet and has permanent properties.
One end of a piece of magnet is called the South Pole and the other end is called the North Pole. This feature of the magnet is used in many electronic devices. Used in directional compass, doorbell, speaker, electric car, generator, dynamo etc.
