The "maglev car" has not yet been developed. The idea of ??the maglev car originated from Cai Yuchen, a female college student in China. Later, after the idea was seen by the German Volkswagen Company, Volkswagen produced it based on this idea. A related car model was released and a promotional video was made for the model.
Although such a car is still in the concept stage, it must be said that this idea is still very valuable. It is said that Volkswagen of Germany invested US$50 million but failed to buy Cai Yuchen’s patent. Cai Yuchen expressed that he wants to keep this invention in China and hopes that China can develop this invention. So is a maglev car possible?
According to experts, it is still very difficult to realize a maglev car. Maglev cars must rely on rich maglev veins underground to provide power for levitation. However, geomagnetic veins with irregular distribution of magnetic poles are not certain. The direction of N pole and S pole. In other words, if permanent magnets with fixed magnetic poles are used, maglev cars cannot be realized using the principle of "same-sex repulsion".
Then superconducting electromagnets need to be used at this time. However, superconducting electromagnets also need to be used in a low temperature environment and a strong external magnetic field environment, which is not possible in current real life. With such conditions in place, it is expected that it will take a long time to truly realize trackless magnetic levitation technology.
