Shima is magnetic levitation 10, and Shima is magnetic levitation

The maglev train is a high-tech vehicle that uses the attraction and repulsive force between the magnetic poles. To put it simply, the repulsive force makes the train hang and the attraction makes the train move.

The train is equipped with electromagnets, and the bottom of the railway is equipped with coils. After being energized, the polarity of the magnetic field generated by the ground coil is always the same as the polarity of the electromagnet on the train, and the two are "repulsive", the repulsive force makes the train levitate, and the coils are also equipped on both sides of the track, and the alternating current makes the coil become an electromagnet. It interacts with the electromagnets on the train to make the train move forward.

The electromagnet (n pole) of the locomotive head is attracted by the electromagnet (S pole) a little earlier on the track, and at the same time is repelled by the electromagnet (n pole) a little later on the track——— one "pushes" and one "pulls".

When the maglev train is running, it maintains a certain gap (generally 1-10 cm) with the track, so it is frictionless, safe, stable and comfortable, and noiseless, and can achieve fully automatic operation.

The service life of maglev train vehicles can reach 35 years, while ordinary wheel-rail trains are only 20 to 25 years. The rail life of maglev trains is 80 years, and that of ordinary rails is 60 years.

My maglev principle: This is my design when I was in school in 1992, but the Internet was not so convenient at that time, I didn't know that there was a maglev train, and when I proposed this theory, it was rejected by my physics teacher. Today, I think it's not outdated, so I'm bringing it up today to discuss with you.

Using permanent magnets to establish levitation force, setting up simple magnetic force on both sides to control the lateral force of the vehicle, and setting up two-way magnets at the bottom to control the movement of objects, my idea is simple in structure, low cost and simple in maintenance.

The maglev train is a high-tech means of transportation that uses the attraction and repulsion of magnetic poles. To put it simply, the repulsive force makes the train hang and the attraction makes the train move.

The maglev train is equipped with electromagnets, and the bottom of the railway is equipped with coils. After the power is applied, the polarity of the magnetic field generated by the ground coil and the polarity of the electromagnet on the train always remain the same, and the two are "repulsive", and the repulsive force makes the train levitate. The rails are also equipped with coils on both sides, and the alternating current turns the coils into electromagnets.

It interacts with the electromagnets on the train to make the train move forward. The electromagnet of the locomotive (n pole) is attracted by the electromagnet (S pole) a little earlier on the track, and at the same time repelled by the electromagnet (n pole) a little later on the track – the result is a "push" and a "pull". When the maglev train is running, it maintains a certain gap (generally 1-10cm) with the track, so it runs safely, smoothly and comfortably, without noise, and can realize fully automatic operation.

The service life of maglev trains can reach 35 years, while ordinary wheel-rail trains are only 20-25 years. The lifespan of the maglev train track is 80 years, and the ordinary rail is only 60 years. In addition, the maglev train reached its top speed within 39 seconds of starting, and the current top speed is 552 kilometers per hour.

According to German scientists**, by 2014, the maglev train will be able to reach speeds of up to 1,000 kilometers per hour after adopting the new technology. The maximum speed of a general wheel-rail train is 300 kilometers per hour.

The maglev train uses the principle of "the same sex repels each other, and the opposite sex attracts", so that the magnet has the ability to resist gravity, so that the car body is completely off the track, suspended at a distance of about 1 cm from the track, and takes off, creating a miracle of almost "zero altitude" space flight.
