On the Auto World website it says "Super III's chassis design features two powerful neodymium traction magnets that can be manually raised or lowered in the chassis to "tune" the car to operate on different tracks."

You can push em around and then hot glue them in place I suppose.

they stay put ok, but I am going to put a dot of hot glue to keep them put
