Electromagnetics is the basic subject of electrical major.Electrical students must master it deeply,and other engineering students should also learn it.At present,the teaching materials of electromagnetism are all explained from the knowledge point itself.Although they are rigorous,they appear abstract,which is not conducive to the understanding of beginners.By comparing with the characteristics of fluid,the important concepts and laws of electromagnetism(Kirchhoff's law and displacement current)are explained.By concreting the invisible and untouchable electricity and magnetism,the distance between students and the knowledge point is shortened to achieve the purpose of rapid understanding and absorption.
