A "magnetic levitation vehicle" appeared in the street, which can run without wheels. Passers-by are dumbfounded

With the development of science and technology, people's travel modes are more and more diversified. Now there are many modes of travel such as high-speed rail, plane, car and subway. However, human beings have not stopped exploring their neighbors and are eager for more efficient ways to travel. Recently, a kind of "magnetic levitation vehicle" appeared on the streets of Sichuan, which was suspended in the air and could run without wheels. The passers-by present were dumbfounded and marveled at the development of science and technology to such a height.

As can be seen from the video, this "magnetic levitation vehicle" is full of science and technology, and its overall shape is a roller, which is somewhat similar to that in science fiction movies. The automatic navigation system is installed inside the car body, which is simple and creative. However, the current magnetic levitation technology has great limitations and must be realized in a fixed orbit. Does this kind of "maglev car" without tracks really exist?

In fact, this is not a real "magnetic levitation vehicle", but a model made by German Volkswagen Company according to the creativity of China female college student Cai Yuchen. It's just a promotional video produced by Volkswagen Germany based on this model. Maybe many people will be disappointed to hear that.

However, this idea is still very valuable. According to reports, Volkswagen invested 50 million dollars to buy the patent of this female college student. But she didn't accept it, saying that this invention should be left to the motherland. She hopes that China's scientific and technological team will develop this invention and use this patent to make contributions to the country.

According to experts, it will not happen overnight to realize the "maglev vehicle". For example, the "maglev vehicle" on the street in the video relies on the rich underground maglev veins in Chengdu to provide suspension power. However, the distribution of magnetic poles in geomagnetic pulse is irregular, because the directions of N and S poles cannot be determined. That is to say, if the maglev vehicle wants to use the principle of "like-poles repel each other", it can't use permanent magnets with fixed poles, but must use superconducting electromagnets. Superconducting electromagnet can maintain diamagnetism under the action of external magnetic field. However, in order to make the superconducting electromagnet work normally, it is necessary to provide a low temperature environment. Moreover, in order to produce strong diamagnetism, superconductors must need a strong external magnetic field, and it is not enough to rely solely on the magnetic field of geomagnetic mines. Therefore, to realize trackless magnetic levitation technology, we must rely on other power assistance. Therefore, I am afraid it will take a long time to wait for the real "maglev vehicle".

However, if the "magnetic levitation vehicle" can really be manufactured, it is actually difficult to realize it in our daily travel. After all, this flying car is more likely to cause traffic accidents every day. I don't think it is possible for the relevant departments to approve the road, right?
