Abstract
The utility model discloses a magnetic suspension globe, comprising a globe body, a magnet and a support bracket provided with an electromagnetic coil on the top. The earth axis lines of the antarctic and arctic poles of the globe body are provided with a bearing, and the earth axis lines of the antarctic and arctic poles of the globe body coincide with the central axis line of the bearing. The outer ring (or inner ring) of the bearing is fixed on the globe body through a spoke or a bearing frame. A support rod fixedly connected with the inner ring (or outer ring) of the bearing is provided with the magnet on the top. As the magnet does not contact with the inner wall of the globe body, a certain interval is arranged between the magnet and the inner wall of the globe body. The mutual attraction between the electromagnetic coil and the magnet makes the globe capable of dealing with a suspension state. Meanwhile, a motor can be arranged on the bottom of the support rod to drive the bearing to rotate, so that the globe body can conduct self-spin simultaneously when the globe is in the suspension state. The utility model with simple structure can conduct the demonstration of the self-rotation of the earth.
