Dongguan magnet strength magnet wholesale mobile phone should be called magnet, English Magnet, magnet now divided into two categories, one is soft, one hard magnetic; soft silicon and software including Dongguan magnetic core; hard magnetic including Alnico, SmCo, ferrite and NdFeB, of which, the most expensive is samarium cobalt magnet, the cheapest is ferrite magnets, NdFeB magnets are the highest performance, but the performance most stable, best temperature coefficient is a powerful phone alnico magnet Products, the user can select different hard magnetic products according to different needs. Performance Dongguan magnets: remanence Br: permanent magnet magnetized to technical saturation, and after removing the external magnetic field, called the retained residual magnetic flux density Br. Coercive force Hc: to technical saturation magnetization of the permanent magnet B is reduced to zero powerful magnets phones, the need to add a reverse magnetic field strength is called magnetic induction coercivity powerful magnets Which phone, referred to as coercivity magnetic energy product BH: represents the magnet gap space in Dongguan. 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 magnets, so called energy product. Magnetic field: Space for generating a magnetic pole surface magnetic field effect of the magnetic field: the magnetic flux density of the permanent magnet surface to a specified location for heavy machinery industry, or for use in large-scale power units, this is also decent. But in today's electronic age crafted, we need a more exquisite stature magnet. But how can we create such a magnet to it? A lot of solid material in electronic and spin interactions between them are too complicated, theoretical physicists want to accurately determine their behavior, almost no chance of winning. Therefore, to produce more excellent magnet relies heavily on the dark magic metallurgists: mixing the various possible elements, and then into the magnetic field, to see how the wheel of fortune will change. Shen Nong tasted a hundred herbs such methods have been tested. 1930s synthetic aluminum - cobalt - nickel-magnet, the energy density is twice that of the best ferrite magnets. But the real breakthrough is still above the 1970s discovered called lanthanides or rare earth elements, beginning with the magnetic potential. These elements in the periodic table is always a separate area, without exception, can contribute a lot of spin parallel to each other and even woven into a piece of electronics. With a mixture of cobalt and rare earth magnets made of samarium, storage or even than aluminum - cobalt - nickel-magnet even twice as high.
