Dongguan magnet magnet heating, should be called magnet, knowledge of English Magnet magnet, magnet now mainly divided into two categories, one is soft, one is hard magnetic; soft silicon and software including Dongguan magnetic core; hard magnetic include Alnico, SmCo, ferrite and NdFeB magnets which decals, SmCo magnet is the most expensive, the most expensive ferrite magnets, NdFeB magnets are the highest performance, but most stable performance, temperature coefficient is best Alnico, the user can select a different hard magnetic products according to different needs. Performance Dongguan magnets: remanence Br: permanent magnet magnetized to saturation technique, and after removing the external magnetic field, the reserved called remanence Br. Coercive force Hc: to technical saturation magnetization of the permanent magnet B is reduced to zero, and the need to increase the magnetic field strength is called reverse coercivity magnetic induction, referred to as the coercive force energy product BH: Dongguan magnet represents gas clearance space. Magnetic energy density established, i.e., the static magnetic energy per unit volume of the air gap. As this energy is equal to the product of Bm and Hm Dongguan magnet, so called energy product. Magnetic field: Space for generating a magnetic pole surface of the magnetic field effect of the magnetic field: magnetic flux density of the permanent magnet surface to a specified location as for component that is iron, cobalt, nickel and other special structure which atoms, atomic magnetic moment itself having general these minerals. molecular arrangement confusion magnetic influence each area will not show magnetic .. but external force (such as magnetic field) molecular orientation, guided to converge on the show .. magnetism. also known as magnetic iron cobalt and nickel are the most commonly used magnetic Basically magnet permanent magnet material divided permanent magnets and soft iron magnetic material is combined with magnetic spin angular momentum of electrons are arranged in a fixed direction is coupled with the current soft (also a plus magnetic method) and other current remove soft magnetic iron magnet will slowly lose heat _ new _ Tong Xin magnetic magnet provided by the Dongguan City, 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.
