A fin is rotatably mounted on the shaft and is, at least in part, a permanent magnet. A switch assembly is provided in the vehicle for effecting in a first portion of the electromagnet an attractive force between the electromagnet and the permanent magnet, and in a second portion of the electromagnet a repelling force therebetween, to cause the fin to rotate on the shaft in a selected direction to effect the guidance of the vehicle.
