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. Ferrite permanent magnet, Permanent magnetic ferrite magnets) And ndfeb magnet difference mainly include the following: 1. Ndfeb permanent magnets ( Permanent magnetic ferrite magnets) Heat resistance is very good, ordinary ndfeb permanent magnets usually only 80 degrees, more than the working temperature of demagnetization will happen. 2. Ferrite permanent magnet, Permanent magnetic ferrite magnets) Stability is very good, it is itself the oxide, is stable, ndfeb permanent magnet is alloy, and its easy oxidation, coating protection must do. 3. Ferrite permanent magnet ndfeb permanent magnets is better than performance. 4. Price than of ferrite permanent magnet ndfeb permanent magnets have many advantage. Electromagnet has extremely extensive application in our daily life. Electromagnet is current magnetic ( The electric magnetic) An application, closely linked with the life, such as electromagnetic relays, electromagnetic crane, maglev trains and so on. Electromagnet can be divided into dc and ac electromagnet two types. If, in accordance with the purpose to divide electromagnet, basically can be divided into the following five kinds: ( 1) Traction electromagnet & ndash; — Mainly used for traction mechanism, open or shut down all kinds of valves, to carry out automatic control tasks. ( 2) Lifting electromagnet & ndash; — Used as a lifting device for lifting ferromagnetic materials such as steel, steel, iron ore. ( 3) Brake electromagnet & ndash; — Mainly used for the motor brake in order to achieve the purpose of accurate parking. ( 4) Automatic electrical electromagnetic system & ndash; — Such as electromagnetic relay and contactor of the electromagnetic system, automatic switch electromagnetic trip and electromagnet operation, etc. ( 5) Other USES of the electromagnet & ndash; — Such as grinding machine magnetic chuck and electromagnetic vibrator, etc. Magnet company is the specialized production ( Ndfeb) Powerful magnet company, has factories in dongguan city based wangniudun pier town.
