【摘要】 均匀带电细圆环是电磁学理论及应用中的基本模型,研究其产生的电场在空间的分布具有重要意义。本文由电势的叠加原理,首先推导出均匀带电细圆环在空间任一点的电势表达式,并用数学软件Mathematic绘出了其电势在空间的分布-等势线的分布;然后由电场强度和电势的关系,得到了空间任一点的电场强度表达式,并进行了数值模拟。更多还原

【Abstract】 A uniformly charged ring is a basic model in electromagnetics and applications, and it is important to study spatial distribution of electric field and electric potential generated by it. The general expression of the electric potential spatial distribution of the uniformly charged ring is obtained based on principle of superposition of electric potential, and the spatial distributions of the isopotential are plotted by Mathematic. The general expression of electric field is obtained by the relation of the electric field and electric potential, and it is analyzed by numerical simulation.更多还原
