Magnet manufacturers about how long to keep the magnet magnetic magnets when we see will feel these are very familiar with, and use, these can provide more convenient for us to use these mainly in industry . So when it comes to the magnet may be a lot of people do not know why these magnet magnetic magnets will become weak, in fact, these are the reasons, we now take a look at the magnet manufacturers to tell us about how long to keep magnetism. Maglev trains are very competitive in the 21st century non-contact surface side rail transport magnets, magnetic levitation train with good ride comfort, safety, speed, efficiency and low pollution, etc., in recent years become the world's developed countries in the high-speed one of the hot research field of transport. To this end, the brake study maglev technology more and more people's attention. High-speed maglev train brake initial velocity when big magnet core, has great momentum in the braking distance to the provisions of such a big transformation and dissipation of energy, any kind of separate mechanical or electrical braking systems are difficult to complete. Therefore magnet boxes, high-speed maglev train braking by regenerative braking, brake friction and eddy current brake pedal composed three kinds of braking. Maglev train running at high speed range eddy current brake braking characteristics flat, braking force, thus becoming the maglev train braking combined in one. In the future, with the continuous improvement of permanent magnet eddy current brake technology, its application is bound on the maglev train more widely. Magnet linked to a new magnetic Xin Tong, a magnet is provided by Xin Tong, Dongguan City, the new magnetic Limited. Xin Tong, Dongguan City, the new magnetic Limited (www.dgxtxmagnet.com/) is Dongguan, Guangdong, magnetic leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the new Tong Xin magnetic leadership with the staff warmly welcome all inquiries to discuss, with new magnetic Tong Xin a better future.
