How to Magnetize Demagnetize Metal Sciencing

24/04/2017  Magnetization is possible only with iron or iron alloys, such as steel. Screwdrivers are commonly magnetized this way to attract screws. Magnetizing. Place the magnet at one end of the piece of metal. The magnet must make as much contact with the metal as possible. Place light pressure on the magnet and rub the metal in one direction only. Magnetization will take some time to accomplish so ...

What Are the Uses of Magnetite? - Reference

29/03/2020  Magnetite can also be used in water filtration systems. A water filtration system with magnetite has a more aggressive backwash in the cleaning phase, as well as the ability to recover the magnetite by using a magnet. It is also used in coal mining operations as a slurry with water to remove the heavier impurities by allowing the less dense coal to float to the surface. The magnetite can be ...

Magnetic Metals Non-Magnetic Metals With Examples

If needed, steel can also be used to make permanent magnets. Let’s take the example of steel EN C15D. This grade of steel contains 98.81 to 99.26% iron. Thus, a very high percentage of this steel grade is iron. Hence, the ferromagnetic properties of iron transfer to steel. Stainless Steel. Some stainless steels are magnetic and some are not ...

Soft and Hard Magnetic Materials - your electrical guide

Soft magnetic materials cannot be used for making permanent magnets because they have narrow hysteresis loops. It has been seen that when carbon is added in material, its hysteresis loop area is increased. That’s why in early days carbon steel was used for permanent magnets. Although it is cheap, magnets made from carbon steel lose their magnetic properties very fast under the influence of ...

The magnetic particle test method of Non-Destructive Examination was developed in the USA, in the 1930s, as a way to check steel components on production lines. The principle of the method is that the specimen is magnetised to produce magnetic lines of force, or flux, in the material. If these lines of force meet a discontinuity, such as a crack, secondary magnetic poles are created at the ...
