The biggest application of neodymium is to make the strongest magnetic material with excellent performance. This kind of magnet is called neodymium iron boron strong permanent magnet. It is the strongest magnetic material with the strongest magnetism found so far. Two magnets smaller than chalk can pass through the palm of a human hand and attract each other. Two small magnet bars that are drawn directly together. It's hard for women to separate them directly. Since this kind of magnet is too strong, many players buy this kind of magnet to do various interesting experiments. For example, use two magnets to crush some common daily necessities, and use super magnets to tug of war.
Of course, such a strongest magnetic material is widely used in reality. This kind of permanent magnet can be used as small as the microphone headset, as large as the high-speed railway ship. It can be said that the discovery and application of NdFeB permanent magnets have brought us a refined and convenient modern life. Our computer needs a hard disk. For the hard disk to work normally, a motor must drive the platters to rotate at a high speed. Such a small motor can carry a large magnetic disk at 7,200 revolutions per minute. To obtain this ability, ordinary magnets cannot do it, and a strong neodymium iron boron permanent magnet must be used. Such a high speed is not its limit.
All the mobile phones we use have a vibration function. The motor that can vibrate inside the mobile phone must be very small, which requires the magnet to be very strong. Of course, this is the territory of the strongest magnetic material. The motor of the car wiper is also very small, but it is very powerful. In addition, some high-end mobile phones have more and more powerful external speakers and better sound quality, but the external speakers are very small. Needless to say, you can also guess, it is also the effect brought by the powerful china neodymium iron boron magnets! In addition, some music stars' customized microphones are very expensive. One microphone can be worth more than one hundred and twenty thousand. This is not only because of the beautiful shell, but also because of the excellent radio effect. Of course, NdFeB strong permanent magnets still play an important role.
Our country vigorously develops new energy vehicles, in which electric vehicles are considered to be the best option to replace fuel vehicles. However, if you want to replace fuel vehicles, you must achieve the performance of fuel vehicles. This requires a car's electric motor to be powerful, energy-saving, and fast. At present, NdFeB strong permanent magnet is widely used in the field of high-end electric vehicles, which brings extraordinary performance to electric vehicles. For example, the BYD Han car newly produced by China's BYD Company can accelerate to 100 kilometers in only 3.9 seconds. What is more frightening is that the Tesla Roadster only needs 1.9 seconds to accelerate from 100 kilometers, which is an achievement that is difficult for a fuel vehicle to achieve.
