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. use of magnetic fields 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 ...
