After magnetization process of magnetic molecules will have the arrangement of the rules. At this point, the magnetic molecular N pole and S pole will be in the same direction to make a magnet with magnetic and magnet. At the same time, the same magnet there instead of equal amount of magnetic poles and poles. Magnets and magnets, it is to point to in the presence of magnetic field of the surrounding and their own internal objects or materials, divided into two categories: natural and artificial. Artificial magnet is usually made of metal alloy, has the strong magnetism. And can be divided into & other; The permanent magnet & throughout; With & other; The permanent magnet & throughout; , i. e. , & other; Hard magnetic & throughout; With & other; Soft magnetic & throughout; 。 Main ingredients: natural magnet ferroferric oxide, chemical formula Fe3O4, often called & other Magnetic iron oxide & throughout; 。 Black crystals with magnetic. Can be seen as ferrous oxide and the compound composed of ferric oxide. Because in the ferroferric oxide crystals are two kinds of different valence state of ions, a third of them are Fe2 +, two-thirds are Fe3 +, is a kind of complex compounds. It does not dissolve in water, also can not react with water. Reaction with acid, not soluble in alkali. Mainly used for making primers and paint, magnetic material used in the electronics industry, also used in the construction industry rust inhibitor. www。 yirongciye。 Com telephone: 86 0769 81313183 contact: Mr Mo mobile phone: 13826919856 preach true: 86, 0769, 81313568 address: China guangdong dongguan dongguan city based wangniudun town pier five chung industrial zone of the magnet, powerful magnets, magnet manufacturers, special-shaped magnet
