磁悬浮高速铁路这种现代新型交通工具,之所以受到人们的青睐,就在于它具有神奇的磁悬浮、推进和导向系统。当今,磁悬浮铁路可按磁悬浮革辆电磁铁磁场类型分为超导排斥型和常导吸引型两大类。超导排斥型是在列车底部,安装有超导电磁铁,在地面上轨道两侧埋没一系列铝环线圈。当列车运行时,给车上超导磁体通电流产生强磁场,地上线圈与之相切割,产生感应电流。感应电流产生的磁场与车上超导磁体的磁场方向相反,两个磁体产生排斥力。当排斥力大于列车重量时,列车就悬浮起来。常导吸引型使用传统电磁铁,通电后产生磁场,因磁极异性相吸,使列车悬浮于轨道上方。磁悬浮列车前进 Maglev high-speed railway this modern new type of transport, the reason why people of all ages, because it has a magical maglev, propulsion and guidance system. Today, maglev railway maglev magnetic levitation magnetic field can be divided into two types of superconducting repelling and often-guided attraction. Superconducting exclusion type is at the bottom of the train, the installation of superconducting electromagnets, buried in the ground on both sides of the track a series of aluminum ring coil. When the train is running, to the car superconducting magnet current generated strong magnetic field, the ground coil with the cutting, resulting in induction current. The magnetic field generated by the induced current is opposite to the magnetic field direction of the superconducting magnet in the car, and the two magnets generate the repulsive force. When the repulsion is greater than the weight of the train, the train levitates. Often used to attract the traditional type of electromagnet, after the magnetic field generated, due to the magnetic polarity of the attraction, so that the train suspended above the track.
