Use of magnetic fields
The natural magnet is a stone found in the process, which attracts small fragments of iron. This stone is the iron oxide (Fe3O4). There is no definite omission of it.

Some substances can be made magnetically by artificial methods, such as iron, steel, cobalt, etc. These are called artificial magnet. They have different oscillations like Ghondalal magnet, magnetic needle etc. Do you know that the power to attract their iron pieces is far more than the natural magnets.
Hence the area around the magnet and in which the effect of magnet can be experienced is called the magnetic field.
Magnetic Susceptibility is the physical amount that explains how easily a substance absorbs magnetism. By using magnetic force, materials such as iron, aluminum etc. can be magnetized.
Let's study about the use of the magnetic field

| how to use magnetic fields |
1. We all know that the oldest use of magnet was done to know the direction by the sailors. Today the compass box is used.
2. Magnet is used to identify iron substances. When iron filings are removed in the eyes of laborers working on the lathe, they are removed with the help of a magnet.
3. A tape recorder has been created for sound recording and reproduction. The magnetic field transmitted in a perpendicular to magnetic substance above the tape can be recorded. Sound, music, speech, etc. can be heard on these tapes and also can be heard later.
4. Videotape can not only be used in the form of transient intensity of the magnetic field, but not only the sound, but also the pictures. The movies can be recorded on the video tape. Any event can be recorded as a magnetic video by video camera.
5. Magnetic memory is very important in the field of computer. The floppy disk also has a coating of magnetic material. The data can be written and deleted from floppy disk with very sensitivity.
6. There is a bar of coating on the back of the ATM card, credit card and debit card. Identification of the user and its code is hidden in this bar. Currency exchange can be done at any time by putting in the machines of the banks and trading establishments.
7. The magnetic field is very important in the electromagnetic field. The use of electromagnetic induction is in the dynamics of trains in generators used in electric houses.
8. Magnetic field is used to accelerate charged particles. These quick particles have great importance in Native experiments.
9. The value of current flowing in more streamlined wires can be read by adding ampere meter without circuit. This is the device based on the magnetic effect of Dhara.
10. In the effect of the magnetic field in the MRI, radio waves of high frequency of different parts of the human body, by absorbing in different proportions, create an image, by which the irregularities are detected in the inner part of the body and treated.
From the above article it is known what is the magnet and magnetic field and where and where the magnetic field is used.
