Abstract
In a rolling element () for the polydirectional travel of a vehicle on a magnetically attractive underlying surface (), a compact, robust and simple design is made possible in that the rolling element () has a spherical element () and at least one permanent magnet (). The spherical element () supports the at least one permanent magnet () in such a way that the at least one permanent magnet () maintains its spatial orientation when the spherical element () rolls on the underlying surface (), and the spherical element () is held in contact against the underlying surface () by the magnetic interaction of the at least one permanent magnet () with the underlying surface ().
