ABSTRACT OF THE DISCLOSURE In the induced repulsion type magnetic suspension railway, superconductive magnets of opposite polarities are alternately set at specific intervals in the longitudinal direction of vehicle, while in the longitudinal direction of track conductive loop coils or con- ductive sheets are continuously set at specific intervals, whereby the repulsion taking place between the eddy current due to a vol- tage induced in said conductive loop coils or conductive sheets by said superconductive magnets and said superconductive magnets levi- tates the vehicle. In such a railway, an additional source to pro- duce a magnetic field of same polarity is provided on the vehicle; and thereby a magnetic flux with the same period as the vehicle vi- bration is applied intersecting said conductive loop coils or cond- uctive sheets on the ground when the vehicle vibrates. Thus an in- duced current is produced by said magnetic flux and, using the mag- netic force developed between this induced current and said magnetic source of same polarity, the vibration of a running vehicle can be damped.
