We have a certain understanding of the magnet, then you know what is the second article magnet it? On this magnet is somewhat incomplete, and qualified open-minded. Is that some products do not affect the use, on the set for the second product . Magnet has applications in many places, such as sintered NdFeB permanent magnet materials from primary grades who praised two kinds of magnetic properties of three parts, the first part of the main that the chemical symbol for the element neodymium ND, the chemical symbol for iron chemical symbol FE and boron B, and the second part is the digital line before the material the maximum energy product (BH) max of the nominal value (in kj / m), the third part is the figure after the slash, coercivity magnetic intensity values ??(in units of KA / m) of the tenth, values ??rounded rounding. Sintered NdFeB material has excellent magnetic properties, widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware and machinery, aerospace and other fields, more common with permanent magnet motors, speakers, magnetic separator, computer disk drives, magnetic resonance imaging equipment instrumentation. Although second-class products and first-class products magnet compared to a little flawed, but not too many demands on the quality of the magnet can still use the product, the second product in general, is very good market prospects magnet.
