Magnetic toy tool

Description: The third generation of rare earth permanent magnet NdFeB is the strongest performance of contemporary permanent magnets. Its value is 5-12 times BHmax ferrite magnets, is 3-10 times alnico magnet; it's the equivalent of 5-10 times the coercive force of ferrite magnets, alnico magnet 5 15 times the magnetic potential is extremely high, it can pick up the equivalent of 640 times the weight of its own weight. As the main raw material of iron NdFeB magnets are very cheap, compared with reserves of rare earth neodymium, samarium more than 10-16 times, so the price is much lower than the samarium cobalt magnet strong magnet industry application editor electro-acoustic field: Speaker, receiver, microphone , alarm, stage audio, car audio. Electronic appliances: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, water meter, sound meter, dry reed pipe, sensors. Motor areas: VCM, CDDVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors. Machinery and equipment: magnetic separation, magnetic separation machine, magnetic crane, magnetic machinery. Healthcare: MRI scanners, medical equipment, magnetic health products, magnetic fuel economy and so on. Other industries: magnetized wax, pipe descaling, magnetic fixture, automatic mahjong machine, magnetic locks, doors and windows magnetic, magnetic bags, leather magnetic toys, tools magnetic, craft gift packaging. Mechanical properties of NdFeB magnets are better than samarium cobalt magnets and alnico magnets, 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), chromium (Cr), epoxy resin (Epoxy) and the like. [1]
