| Abstract: | From Chengdu Geomagnetic Station into high-speed rail lines vertical distance of about 1.5 km,the use of digital flux-gate magnetometer GM4. The results of indicate that the moving of trains on the city railcar disturbs the environment of geomagnetic observation and the influence basically disappears by 10 km from the railcar line. The disturbance results from the leakage of electric current by railway and transmit electricity line. |
