Maglev trains since about 200 years ago, Stephenson's "Rocket" steam locomotive railroad came the most fundamental breakthrough technology. Maglev trains today seems a fresh look at things, in fact, it's theoretical preparation has a long history. Maglev technology research from Germany, early in 1922 the German engineer Hermann Kemper put forward the principle of electromagnetic levitation, maglev train and apply for a patent in 1934. After the 1970s, with the industrialized world continue to strengthen the country's economic strength, to improve transportation capacity to meet the needs of their economic development, Germany, Japan, the United States, Canada, France, Britain and other developed countries have begun to conduct magnetic levitation transportation system planning development. Application Chinese NdFeB magnets NdFeB application follows the application of high-tech products accounted for 37% of the area of ??micro-electromagnets, such as magnetic resonance imaging (MRI), the phone vibrates, hard drive voice coil (VCM), disc (DVD , CD-ROM) drive shaft, power tools, electric vehicles, inverter air conditioner engine. Application of traditional areas of affordable products accounted for 63%, such as audio devices, magnetic adsorption devices, magnetic devices, magnetic devices. Military applications of magnetic field magnetic field of the same in the military has been widely used. For example, ordinary mines or mines explode only when in contact with the target, and therefore a limited role. If the magnetic sensor is installed on a mine or mines, tanks or warships are due when the steel manufactured in their proximity (without touching the target), the sensor can detect changes in the magnetic field so that mine or mine explosions, improved lethality. In modern warfare, the battle to win control of the air is one of the key to victory. But the aircraft during the flight can easily be detected enemy radar to electromagnet manufacturers, which have greater risk. In order to avoid enemy radar monitoring aircraft surfaces can be coated with a special magnetic material - absorbing material, which can absorb electromagnetic waves emitted by the radar, making radar aircraft touched electromagnetic waves occur after only a few reflections magnets price, and therefore enemy radar can not detect radar echoes, can not find the aircraft, which makes the aircraft reached a stealth purposes. This is the famous "stealth aircraft." Stealth technology is a hot topic in the world in the field of military research. American F117 stealth fighter is an example of the successful application of stealth technology. In the US "Star Wars" program, there is a new type of weapon "Electromagnetic weapons" research and development. Is the use of conventional artillery ammunition explosion instant expansion thrust generated when the shells quickly accelerate the introduction of bore. The guns are the shells on the solenoid, the solenoid is energized, the magnetic field generated by the solenoid on the shells will have a huge impetus to the shells fired. This is called the guns. There are similar electromagnetic missiles. Powerful magnets, magnet Fujian, Xin Tong new magnetic provided by the Dongguan City, Tong Xin magnetic Limited.
