The world globe (1) houses a magnetic body (2) or (3) respectively in the shape of a truncated sphere or cone closely fitting to the inner surface of the globe on the south pole side, with the poles of the magnetic body directed exactly toward the poles of the globe. The magnetic body has a through-hole (4) which receives a bolt (5) with a spherical head and a tube bolt (6) respectively screwed from the both ends of the hole (4). The center of gravity of the whole globe is arranged to be at the spherical center of the bolt (5). The globe set on an oblique plate (1) rotates on its axis and also revolves in the orbital motion.
