Maglev Globe Works
Use magnetic levitation globe sex repulsion principle applied by the permanent magnet electromagnetic methods to make a globe floating in midair. The bottom of the globe there is a permanent magnetThe baseInternal position corresponding with a set of metal coils, the current through the metal coil becomes an electromagnet. Repulsive force solenoid magnet at the bottom of the globe between the globe suffered can counteract gravity, so the globe can float in the air.
Why can not af down globes can be fixed in one place? Since the middle of a group of Hall coil detector can detect changes in the magnetic field of the magnet bottom of the globe. Deviation from the equilibrium position when the globe, the Hall sensor is triggered by changes in the magnetic field of the magnet bottom of the globe, there will be a compensation current. When the compensation current to flow out of position orientation Globe metal coil, metal coil magnetic field increases, the globe can be retracted position of equilibrium, so the globe can be always maintained in the same position in suspension.
