摘要
在大学物理教材中普遍存在着把电场和磁场分离开来的一个不合理的认识,并由此派生出了一些不合实际的说法。文章指出,电磁波的传播过程和电磁感应现象并不简单地是电生磁、磁生电的过程,电场和磁场并非独立的两种物质,而是一种特殊物质(即电磁场)的二种属性或二种表现形式。
An inconsequence congnition has generally existed in college physics teaching material that separates electric field from magnetic field,which has derived some discrepan-cy. This article points out that the spreading course and response of electromagnetism field are not simply the course in which electricity can produce magnetism and magnetism can pro-duce electricity. Electric field and magnetic field are not two absolute different substances but two attributes or behaving forms of a sort of especial substance, namely electromagnetism field.
