[0006] In addition, the maglev train is different from the wheel-rail train. It is equipped with a linear motor on the track. When it floats and drives, the electromagnetic radiation on the track will be much larger than that of the wheel-rail and medium-low speed maglev train. The frequency is similar to the induction wireless frequency, and it is also around tens of KHZ, which greatly reduces the accepted signal-to-noise ratio
