The Design of Magnetic Levitation Showcase for Small Commodities

Abstract:

This paper combines the maglev concept and commodity display. The commodity and the permanent magnet are hanged together and put under electromagnet, the distance from permanent magnet to magnet detected by Holzer components, and then the magnet position signal is amplified and formed a strong negative feedback control loop which can control the current of solenoid coil, at last we can hang on the different weight goods through changing the size of the electromagnet attraction.
