Description	Journal: Iop Conference Series: Earth and Environmental Science At present, there are few researches on the electromagnetic exposure of superconducting maglev train to passengers. In order to supplement these deficiencies, the finite element simulation software COMSOL is used to model the Halbach track and the superconducting maglev train and guide rail of the Federal University of Rio de Janeiro in Brazil. The simulation results show that the train can get off the train when it is stationary on the straight track Electromagnetic exposure of customers. The results show that: when the train is stationary and the suspension height is 5 mm, the maximum values of magnetic flux density in the body of the three passengers are 527μT, 240μT and 77.7μT respectively, and the farther the passenger is from the guide rail, the magnetic flux density in the body tends to decrease. These values are lower than the public electromagnetic exposure limit recommended by ICNIRP, which indicates that the magnetic field generated by the superconducting magnetic levitation permanent magnet track will not pose a health risk to the passengers in the vehicle.
