摘要
本文介绍了使用钕铁硼磁体自制的几种单极电动演示仪器,包括:单极电动机、单极电动小车、单极电动风扇。给出了演示仪器的结构图,用经典电磁理论分析了单极电动的原理。该演示仪器制作方法简单且成本低,适合电磁学的教学使用。
The paper introduced several self-made homopolar machine demonstration instruments by using NdFeB magnets, such as homopolar motor,homopolar electric vehicle,homopolar electric fan. Not only gaving the instrument design, the paper also analyzed the principle of homopolar machine by using classical electromagnetic theory. The demonstration instrument have the advantages of simple production methods and low cost,it was suitable for the teaching of Electromagnetism.
