Question:
maglev train work?

Answer:
high-speed maglev train is a 20th century invention, its principle is not difficult. It is the use of a magnet for “same-sex repulsion, attraction heterosexual” in nature, so that magnets have the ability to resist gravity, that is, “magnetic suspension.” Scientists will be “suspended magnetic” The principle of the use of the railway transport system is completely out of the train track and suspension travel, a “non-round” train up a few hundred kilometers per hour. This is the so-called “magnetic levitation train.” As the magnet

have heterosexual same-sex attraction and repulsion in two forms, so there are two types of maglev train the appropriate forms: One is the use of same-sex repulsion magnet designed electromagnetic principles of operation of the maglev train system, which uses the vehicle superconductors electromagnet with the magnetic field formed by the coil track formed between the magnetic field generated by the repulsion force, so that the operation of the railway vehicle suspension; another is to use the magnet design of the opposite sex attraction and the principle of operation of the electric maglev train system It is at the bottom and on both sides of the body back up at the top of the magnet is installed in the T-shaped rail part of the top and bottom respectively伸臂counterproductive steel panels and sensors to control the solenoid current, so that between the electromagnet and the rail maintain 10 mm (plus or minus error of 2 mm) gap, and the attractiveness of rail steel with the gravitational balance of the vehicle so that the body suspended in the guide surface running lane. maglev train

is a product of modern high-tech development. The principle is that the use of electromagnetic force to offset gravity, through the linear motor for traction, so that the train tracks suspended in the run (suspension gap of about 1 cm). Involved in their research and manufacture of automatic control, power electronics technology, straight-line propulsion technology, machinery design and manufacturing, fault monitoring and diagnosis, and many other disciplines, technology is very complex, scientific and technological strength of a country and an important indicator of industrial standards. It is compared to the general wheel-rail train, with low noise, no pollution, safe and comfortable and high-speed high-performance characteristics of a “zero height of aircraft,” the reputation, is a promising new means of transport, particularly for urban rail transit. Suspended by magnetic levitation train is divided into different general repulsion and suction-type two, according to the operating speed and high-speed and low speed of the points.

“若即若离” maglev train is the basic working condition. Maglev trains use electromagnetic force to offset the Earth’s gravity, so that suspended in the train track. Running process, the body and the track in a “若即若离” state of magnetic levitation gap of about 1 cm, hence the “zero height of aircraft,” the world. It is compared to the general wheel-rail train, with low noise, low power, non-polluting, safe and comfortable and high-speed high-performance characteristics, is considered to be a promising new means of transport.

问题:
磁悬浮列车的原理是什么？

回答:
高速磁浮列车是20世纪的一项技术发明，其原理并不深奥。它是运用磁铁“同性相斥，异性相吸”的性质，使磁铁具有抗拒地心引力的能力，即“磁性悬浮”。科学家将“磁性悬浮”这种原理运用在铁路运输系统上，使列车xx脱离轨道而悬浮行驶，成为“无轮”列车，时速可达几百公里以上。这就是所谓的“磁浮列车”。

　　由于磁铁有同性相斥和异性相吸两种形式，故磁浮列车也有两种相应的形式：一种是利用磁铁同性相斥原理而设计的电磁运行系统的磁浮列车，它利用车上超导体电磁铁形成的磁场与轨道上的线圈形成的磁场之间所产生的相斥力，使车体悬浮运行的铁路；另一种则是利用磁铁异性相吸原理而设计的电动力运行系统的磁浮列车，它是在车体底部及两侧倒转向上的顶部安装磁铁，在T形导轨的上方和伸臂部分下方分别设反作用板和感应钢板，控制电磁铁的电流，使电磁铁和导轨间保持10毫米（正负误差2毫米）的间隙，并使导轨钢板的吸引力与车辆的重力平衡，从而使车体悬浮于车道的导轨面上运行。

磁悬浮列车是现代高科技发展的产物。其原理是利用电磁力抵消地球引力，通过直线电机进行牵引，使列车悬浮在轨道上运行（悬浮间隙约1厘米）。其研究和制造涉及自动控制、电力电子技术、直线推进技术、机械设计制造、故障监测与诊断等众多学科，技术十分复杂，是一个国家科技实力和工业水平的重要标志。它与普通轮轨列车相比，具有低噪音、无污染、安全舒适和高速高效的特点，有着“零高度飞行器”的美誉，是一种具有广阔前景的新型交通工具，特别适合城市轨道交通。磁悬浮列车按悬浮方式不同一般分为推斥型和吸力型两种，按运行速度又有高速和中低速之分。

“若即若离”，是磁悬浮列车的基本工作状态。磁悬浮列车利用电磁力抵消地球引力，从而使列车悬浮在轨道上。在运行过程中，车体与轨道处于一种“若即若离”的状态，磁悬浮间隙约1厘米，因而有“零高度飞行器”的美誉。它与普通轮轨列车相比，具有低噪音、低能耗、无污染、安全舒适和高速高效的特点，被认为是一种具有广阔前景的新型交通工具。特别是这种中低速磁悬浮列车，由于具有转弯半径小、爬坡能力强等优点，特别适合城市轨道交通。
