Product Description

Suspension globe using maglev scientific principles, globe in without any supported and contacts electric air rotation, show the true state of earth, with unique visual effect, give a person with peculiar novel feeling and mental enjoyment. At the same time with high appreciation and practicability, earth sphere as standard world map and seven continents, four oceans, world boundary, and the important city panorama of the territory, mixed entertainment, melts the knowledge and fun at an organic whole feeling of the high-tech products clouded charm. Is your friends and relatives of the best gift (also put in a perfect and do the table delicate dynamic decorations) Maglev globe working principle Maglev globe using current magnetic make globe floating in space. Globe top a magnet, circular plastic box and its apex with a metal coil, metal winding through the current will become an electromagnet. Electromagnet and globe top magnet between suction offset globe by gravity, thus globe can floating in space. With the hand lightly touching globe make its deviation balance position, hand away after a globe can still be back into balance position will not drop, this is using negative feedback mechanism. Globe bottom also has a magnet. Plastic box internal bottom a hall detectors, can detect globe bottom magnet magnetic field changes. Globe deviation balance position, hall detector detect globe bottom magnet magnetic field changes, will produce a compensation current. The compensation current flow to the plastic box top wire, wire magnetic field increase, but will a globe back to balance position. Gently turning globe and sustainable keep running, it can use the principle of inertia (say, deeper basis momentum conservation principle) explanation. Globe by external zero-sum, along with a fixed rate will therefore fixed directions.
