要約(英語): When a magnetic levitation rail carrying a superconducting coil moves at high speed, an electromagnetic induction voltage is generated in the surrounding telecommunication line due to Faraday’s electromagnetic induction. This phenomenon is analyzed by AC / DC module of COMSOL Multiphysics. The telecommunication line is modeled for a common mode flowing in a loop between the telecommunication line and the ground. As a result of examining the structure dependency on the induced voltage of the telecommunication line loop, if there are two bogies, It was clarified that the induced voltage becomes a voltage close to zero if the length of the telecommunication line is equal to the bogie interval, and a voltage twice the normal induced voltage is generated when the length of the telecommunication line is slightly shorter or longer than the bogie interval.
