【Abstract】 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.更多还原
