Principle of magnetic suspension globe
Magnetic suspension globe makes the globe float in mid-air through current magnetic effect. There is a magnet on the top of the globe and a metal coil on the top of the round plastic frame. A metal coil becomes an electromagnet when an electric current passes through it. The attraction between the electromagnet and the magnet at the top of the globe can counteract the gravity on the globe, so the globe can float in mid-air. Gently touch the globe with your hand to make it deviate from the equilibrium position. After the hand is removed, the globe can still return to the balance position without falling, which is based on the negative feedback mechanism. There is also a magnet at the bottom of the globe. There is a Hall detector at the bottom of the plastic frame, which can detect the magnetic field change of the magnet at the bottom of the globe. When the globe deviates from the equilibrium position, the Hall detector detects the change of the magnetic field of the magnet at the bottom of the globe, which will generate compensation current.
Magnetic suspension globe is mainly composed of permanent magnet, iron core, coil, magnetic field sensor, power amplifier and controller. When the globe is in a balanced position, the current through the coil winding is i0, and the gap between the globe and the top is x0. Electromagnetic attraction is in balance with the attraction of permanent magnets and the gravity of the earth. When the globe moves downward under the downward disturbing force, the sensor detects the displacement of the globe from the equilibrium position, the controller converts this signal into a control signal, and the power amplifier converts the control signal into a control current i0+Δ i. Therefore, the electromagnet is more attractive and drives the globe back to the original equilibrium position.
