列车为什么会浮起来 ?稍有物理知识的人都知道 ,把两块磁铁相同的一极靠近 ,它就相互排斥 ,反之相吸。磁悬浮列车就是利用这种排斥力使列车悬浮在轨道上方 ,又利用吸引力让它开动。由于列车和轨道之间没有直接接触 ,大大减小了运行阻力 ,达到高速运行。磁悬浮列车分为常导型和 Why did the train float? Someone with a little physical knowledge knows that when one and the other of two magnets are close together, it repels each other and vice versa. Maglev train is the use of this repulsion so that the train floats above the track, but also use the attractive force to start it. As there is no direct contact between the train and the track, the running resistance is greatly reduced and the high speed operation is achieved. Maglev train is divided into normally-guided and
