Detailed Product Description: | The main ingredient known as magnet magnet, refers to the presence of the magnetic field around the object or material and their own internal, divided into two categories of natural and man-made. Artificial magnets usually made of a metal alloy, having a ferromagnetic. Can be divided into a "permanent magnet" and "non-permanent magnet" Rally magnet, or "magnetic hard" and "soft." Natural magnet main ingredients: iron oxide, the chemical formula Fe3O4, often referred to as "magnetic iron oxide." Having a magnetic black crystals. Ferrous oxide and iron oxide compounds can be regarded as. Because the iron oxide crystals in the presence of two different valence states of ions, one third of Fe2 +, two-thirds of Fe3 +, is a complex compound. It is insoluble in water, it can not react with water. React with acids, alkali-insoluble. The main system for primer and topcoat magnets, magnetic materials for the electronics industry, but also for rust in the construction industry. Demagnetization powerful magnets will it? NdFeB permanent magnet known, stands to reason that demagnetization and time does not matter, the main cause of NdFeB demagnetization has two factors, temperature and oxidation, high temperature above the Curie temperature (300 degrees Celsius) will lose magnetism. If the protection is not good to be oxidized, they would lose magnetism, and this is the biggest reason NdFeB failure during use. However, in general use, the environment in general, then toys with magnets, only consider the loss of magnetic oxide, with a 3 to 5 years is not a problem. Protect relatively good, with more than 10 years is no problem. Magnet composition is substantially iron, cobalt, nickel and the like minerals, of which the magnet because of the special tool atomic structure of the comparison, very special, which itself has a magnetic moment, so the ranking general magnet atom is very messy, but if To the magnetic interaction region, then it does not show a magnetic. Now let's use that would be widely a lot, such as a motor or a generator and the like, we have a hard top with computer uses a magnet, as well as the door above the door smoking, car speakers, refrigerator, speaker horn there is also a magnet figure, now some chess is also useful to the magnet, we everyday phone, mobile phone and so many things have to use a magnet, so that the magnet use is very extensive. Toys with magnets | New Tong Xin magnetic | Zhuhai, Dongguan City, the new magnet is provided by Tong Xin magnetic Limited. Xin Tong, Dongguan City, the new magnetic Limited (www.dgxtxmagnet.com/) is Dongguan, Guangdong, magnetic leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the new Tong Xin magnetic leadership with the staff warmly welcome all inquiries to discuss, with new magnetic Tong Xin a better future. |
