Abstract: The invention relates to a globe comprising a contactless and magnetically held globe sphere. Said globe comprises an electric control device for an electromagnet, which is connected on the inlet side thereof to a magnet field sensor, especially a hall-probe, and which controls the position of the glove sphere by switching the electromagnet on an doff or by controlling the current passing through the electromagnet according to the output signals of the magnet field sensor. A microcomputer, which is supplied with the output signal of the magnet field sensor, is provided in order to control a non-oscillating position of the globe sphere. The microcomputer comprises at least one memory-counter which is used to detect on/off positions and /or a device which is used to detect a current passing through the electromagnet or the voltage applied to the electromagnet during at lest one defined period of time.

Abstract: A cartographic device consists in particular of a globe inside which is placed a driving and controlling mechanism able to move a point radiator (42) along the inner wall of the globe in such a way that a point of light visible from the outside and movable at will in the horizontal and vertical directions indicates the geographical location of a place the name of which has been entered in the computer arranged in the base of the globe. The device is controlled by a permanently programmed micro-computer connected to the stepping motors (31, 41) of the mechanism.
