As the main raw material of iron NdFeB magnets are very cheap, compared with reserves of rare earth neodymium, samarium 10-16 times more powerful magnet handset manufacturers, so the price is much lower than the samarium-cobalt magnets. Mechanical properties than samarium cobalt magnet NdFeB magnets and alnico magnets have a good professional phone magnet strength, easier cutting and drilling and machining complex shapes. Inadequate NdFeB magnets is its poor temperature performance, high temperature magnetic loss is large, the maximum operating temperature is lower. Generally around 80 degrees Celsius, after special treatment magnet, its maximum operating temperature up to 200 degrees Celsius. Because the material contains large amounts of neodymium and iron, it is easy to corrosion is one of its major weaknesses. So NdFeB magnets have the surface coating. Nickel can be electroplated (Ni), zinc (Zn), gold (Au) strength magnets phone, chromium (Cr), epoxy resin (Epoxy) and the like. NdFeB magnets widely used in the aerospace industry, electronics, electrical, instrumentation, medical and other fields. And the use of non-technical areas are increasingly being used, such as adsorption magnets, toys, jewelry and the like. 18. Q: Why is a magnet for broke after the, N / S pole redistributes? A: Whether a magnet broken into many pieces, each piece still has a N, S two poles, and even the size of the magnetic atoms are the same. In fact, the bulk magnet is constituted by a plurality of small magnets. Although the magnetic and electric there are many similarities (for example, a lot of small magnets like kinematics law by a pair of positive and negative charge is an electric dipole), but one thing is fundamentally different from that positive and negative charges can exist independently , but the N, S poles can not exist alone, so there is no problem of redistribution. Essentially magnetic and electric are inseparable, powerful phone original magnet Generally, magnetic charge is caused by the movement, whether magnets or electromagnets are the result of the movement of the charge. In modern physics theory, it is possible to obtain a magnetic monopoles exist conclusion, but so far have not found any magnetic monopoles. It is said that under extreme conditions, such as the early universe, the Big Bang some point there may be too magnetic monopoles, which is trying to find scientists are trying to answer.
