Hengdian Kim Dae-magnetic magnet factory --- without basic knowledge of how to identify a magnet marked Arctic? Obviously just by eye is unable to distinguish. You can use the compass close to the magnet, pointing pointer will point to the Earth's magnetic North Pole South Pole. How safe handling and storage of magnets? Always be very careful quality NdFeB brand, because the magnets will absorb yourself together, you may pinch your fingers. There also may be damaged due to collision magnet itself (knocked knocked corners or cracks) is a magnet for attracting each other. Away easily magnetized magnet NdFeB manufacturers of high quality goods, such as floppy disks, credit cards, computer monitors, watches high quality NdFeB, cell phones, medical equipment. Magnet away from the pacemaker. Larger size of the magnet should be added between each piece of plastic or cardboard shims to ensure that the magnets can be easily separated. Magnets should be stored in a dry, heated environment. Hengdian Kim Dae-magnetic ----- how to define the performance of the magnet? There are the following three performance parameters to determine the performance of the magnet: remanence Br: permanent magnet magnetized to technical saturation, and after removing the external magnetic field, the reserved called remanence Br. Coercive force Hc: to technical saturation magnetization of the permanent magnet is reduced to zero quality NdFeB B dealers, the need to increase the magnetic field strength is called reverse coercivity magnetic induction, referred to as the coercive force energy product BH: represents the magnetic energy density in the air gap space magnets (two pole magnet space) established, i.e., the static magnetic energy per unit volume of the air gap. As this energy is equal to the product of the magnet Bm and Hm, so called energy product.
