What is the principle of magnetic levitation what is a magnetic levitation train

What is the magnetic levitation train and what is its working principle
Electromagnetic levitation train (attraction) the electromagnetic levitation train uses electricity to make electromagnets produce ferromagnetism, uses the attraction of electromagnets to separate the track and carriage, and controls the size of levitation gap by changing the excitation current. The maglev train in Shanghai is based on this principleWhat is the principle of magnetic levitation
The suction type is based on the principle that two magnets attract each other. The electromagnet is placed under the track and fixed on the car body bogie. A strong magnetic field is generated between the two and the train can be suspended when they attract each other. This kind of magnetic levitation train can maintain a stable suspension state whether it is stationary or movingMagnetic levitation principle
The maglev train is equipped with electromagnets, and the coil is installed at the bottom of the railway. After power on, the polarity of the magnetic field generated by the ground coil is always the same as that of the electromagnet on the train, and the two "repel each other", and the repulsive force makes the train levitate. Coils are also installed on both sides of the rail. Alternating current turns the coils into electromagnetsWhat is the principle of maglev train
The third principle is that magnets will interact with each other. The same polarity repels each other and the different polarity attracts each other. Maglev train is mainly composed of suspension system, propulsion system and guidance system. Although the propulsion system independent of magnetic force can be used, in most current designs, the functions of these three parts are completed by magnetic forceWhat scientific principles does magnetic levitation technology rely on
But the scenery is good and there are many passengers. Considering this factor, it is feasible to build maglev in the airport. The speed of medium and low speed maglev train is 30km/h, which is not fast. A quiet, stable and comfortable train can be built into a scenic spot line. The simplest electromagnetic levitation scheme is "pull-up magnetic levitation"What is the principle of maglev railway
The principle of magnetic levitation railway: it uses the nature of "the same sex repels and the opposite sex attracts" to make the magnet have the ability to resist gravity, that is, "magnetic levitation". Scientists have applied the principle of "magnetic levitation" to the railway transportation system, making the train completely off track and levitated, becoming a "wheelless" trainWhat is the principle of maglev train
The principle of maglev train is not profound. It uses the nature of "the same sex repels each other and the opposite sex attracts each other" to make the magnet have the ability to resist gravity, that is, "magnetic suspension". Scientists have applied the principle of "magnetic levitation" to the railway transportation system to make the train completely off track and levitateWhat is the principle of levitation
According to the prediction of German scientists, by 2014, the speed of maglev train will reach 1000 kilometers per hour after adopting new technology. The maximum speed of a general wheel rail train is 300 kilometers per hour. The magnetic levitation train uses the principle of "the same sex repels each other, and the opposite sex attracts each other", so that the magnet has the ability to resist the gravity, and the car body is completely off the trackWhat is the principle of magnetic levitation
The attraction of the guide rail steel plate shall be balanced with the gravity of the vehicle, so that the vehicle body can be suspended on the guide rail surface of the lane. Maglev train is the product of modern high-tech development. The principle is to use the electromagnetic force to counteract the earth's gravity, and use the linear motor to pull, so that the train can be suspended on the track (the suspension gap is about 1 cm)
