摘要
从点电荷的场强公式出发,根据狭义相对论中场强张量的变换,推导出了静电场和稳恒电流磁场的诸定律,使学生对电场和磁场的统一性有了更为深刻的认识.
From the formula for the field strength of a point charge,by means of the transformation of the field strength tensor in the special theory of relativity,the laws of electrostatic field and magnetic field of steady currents are derived in this paper to give the students a better understanding of the consistency of electric field and magnetic field.
