What is Permanent Magnet? And the method of making it and its use

permanent magnet in hindi: friends welcome to my website, what is permanent magnet? And complete information has been given about the method of making it and its use, if you want to get information, then read this post completely.

what is permanent magnet

Permanent magnets are made from steel. A steel rod once magnetized is not easily demagnetized because the holding power of steel is much higher than that of soft iron.

method of making permanent magnets

To make a permanent magnet, steel, cobalt and nickel metals are needed, by mixing them this magnet is made and the magnetizing power of this magnet does not dissipate quickly, hence it is called a permanent magnet.

uses of permanent magnets

  1. Permanent magnets are used in electric meters.
  2. It is also used in galvanometer, ammeter and voltmeter.
  3. Permanent magnets are also used in magnetic compass boxes.
  4. use this magnet dc motor And also in big generators.
  5. They also use magnets in sound speakers.

difference between electromagnet and permanent magnet

electromagnet permanent magnet
1. It has more powerful magnetic force. It has a less powerful magnetic force.
2. In this, the magnetic property ends as soon as the current is stopped. It retains its magnetic properties for a long time.
3. Its power can be increased by changing the number of turns in the coil. Its power remains fixed.
4. Electromagnet is made from soft iron. Permanent magnets are made from steel.
5. This produces a magnetic field only as long as the current flows in the coil, that is, the magnetic field is temporary. The magnetic field produced by this is permanent.
6. The polarity of the ends of an electromagnet can be changed. The polarity of the ends of a permanent magnet cannot be changed.

What is a permanent magnet made of?

final conclusion– What is permanent magnet of the information I told you, hope you liked it, if you have any question then you can ask me on the comment, I will be happy to answer your question thank you.
