Leakage magnetic field generated by the air-cored reactor will produce electromagnetic pollution in the metro system, therefore, magnetic shielding of the antimagnetic plate is of crucial importance. First, the three-dimensional finite element model of the air-cored reactor was built. Second, the distribution of the leakage magnetic field without antimagnetic plate was analyzed and compared with the results with antimagnetic plate. In addition, the influences of the antimagnetic plates with different material and different size on the flux density at the different height inside subway cars were investigated. Finally, the on-board test of the designed anti-magnetic board was carried out. The experimental results showed that the designed anti-magnetic board met the requirement that the air gap flux density at 30 cm above the floor inside the compartment was less than 0.8 mT.
