Abstract

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.
