The main component of the magnet

- Nov 25, 2017 -

Magnets, also known as magnetite, refers to the object or material that has a magnetic field in and around itself and is divided into two major categories, natural and man-made. Artificial magnets are usually made of metal alloys, with strong magnetic. Can be divided into "permanent magnets" and "non-permanent magnets", that is, "hard magnetic" and "soft magnetic." The main components of natural magnet: Ferrosoferric oxide, chemical formula Fe3O4, often called "magnetic iron oxide." Magnetic black crystals. Can be seen as a combination of ferrous oxide and iron oxide compounds. Due to the presence of two different valence ions in the crystal of ferriferous oxide, one third of them are Fe2 + and two thirds are Fe3 +, which is a complex compound. It is insoluble in water and does not react with water. Reacts with acids, insoluble in alkali. Primarily used in the manufacture of primers and topcoats, magnetic materials for the electronics industry, but also for the construction industry, rust inhibitors. This is called the main component of the magnet.
