Description: Detailed Product Description These floating objects are called floating body in which permanent magnets are put. Our product is equiped with a suitable sensor and controlling circuit. When the sensor feels the floating body has downward tendency, it give signal to increase the value of the electric current passing through the upper electric magnetic coil, so to increase its attracting force to prevent the downward tendency. If the floating body has A upward tendency, the electric current of the coil will be decreased, so the upward draw force is decreased to prevent the body`s upward tendency. With our naked eyes, we can not distinguish the samll motion of the floating body. The rotation of the body is also generated by the rotation of the magnetic field controlled by the electric circuit, acting to the magnet in the body. That produce pushing and drawing forces, so the floating body keep rotation automaticly. We have a wide range of product series. Series used as school teaching tools(terrestrialglobe) series used for advertising purpose,(cocacolacan)series Used as crafts, series used as gifts and toys.
