With the development of high-tech industries, industrial demands for rare earth
has increased greatly. Neodymium is the fourth element, and it is the most quantity demanded element in rare earth. The biggest application of neodymium is to manufacture magnets with excellent performance. This kind of magnet is called NdFeb magnet(neodymium magnet), which is the strongest magnetic permanent magnet that has been found.
Today we will take a look at the application of NdFeb magnets. A computer hard disk wants to work properly, it must have an electric motor to turn the disk at high speed. Such small motor can carry a large disk at 7,200 revolutions per minute. In order to obtain this amazing ability, the general magnet cannot do that, must use neodymium magnets. The motor in Mobile phone internal playing vibration function of must be very small, which requires the magnetism of the magnet is very strong, of course, it is the territory of NdFeb magnet. In addition, for microphone we generally used, NdFeB magnet is still playing an important role. Electric cars are seen as the best alternative to gas-powered cars. But to replace a petrol car, it has to match the performance of a petrol car. This requires the motor of the car has strong power, energy saving and fast speed.
At present, Ndfeb magnets are widely used in the field of high-grade electric vehicles, which have brought extraordinary performance to electric vehicles' motors. High-speed trains, bullet trains, subways and other rail vehicles are also driven by electric motors. Among them, the motors made of NdFeb magnet will occupy a large share in the future. And that's not all. There is now a tendency for ships at sea to be driven by electric motors. Besides, Ndfeb magnets have a very wide range of applications in the field of wind power generation. And in the field of small household appliances, medical equipment, robotics and aerospace, you can often see the figure of Ndfeb magnets. China is the country with the largest rare earth reserves, the country with the largest output of NdFeb magnets, and the country with the most advanced technology accumulation. Let's look forward to its development together.
