摘要
通过库仑定律和麦克斯韦方程推导出有限长均匀带电直线的电场线方程和等势线方程,并利用绘图软件Winplot画出了电场线与等势线函数图像,直观地表现了电场的特点.
In this paper, we derive the electric field line equation and the equipotential line equation of the uniformly charged straight - line by Coulomb's law and the Maxwell Equation. Then we plot the image of the electric field and the equipotential line with the mapping software Winplot and give an intuitive presentation of the electric field.
