为什么有两个关于电场强度和由匀速运动的点电荷产生的magnetic induction的公式？
Why two formulas for the electric field intensity and the magnetic induction created by a uniformly moving point charge?
摘要：
本文推导了匀速运动点电荷产生的电场强度和磁感应强度。推导是根据运动电荷的电场和磁场在真空中以速度$c$从电荷传播的事实。推导是为了解点电荷静止系中空间、时间和场的变换以及库仑定律的特殊观众量身定制的。它避免了麦克斯韦方程组的使用和延迟势的概念。
英文摘要：
A derivation of the electric field intensity and of the magnetic induction generated by a uniformly moving point charge is presented. The derivation is in accordance with the fact that the electric and magnetic fields of moving charge are propagating from the charge with speed $c$ in empty space. The derivation is tailored for a special audience who knows the transformation of space, time and fields and Coulomb's law in the rest frame of the point charge. It avoids the use of Maxwell's equations and the concept of retarded potential.
