By utilizing the same polarity repulsion between permanent magnets,a magnetic potential well was constructed to design and manufacture an unfallable pole device with adjustable height and anti-slip bottom. The device exhibits strong anti-interference ability,good stability,simple structure,and clever design. The magnetic constraint between permanent magnets does not require external power supply,and has advantages such as contactless control,energy conservation,and low cost.
