利用Matlab软件数值模拟均匀带电椭圆形环在中心轴线上的电势及电场分布

The Arrangement of Electric Field Intensity and Different Position Electric Field Energy of the Elliptical Ring with Positive Electric Charge in the Central Axis

在直角坐标系中分别表示出了均匀带电椭圆形环在中心轴线上任意位置处的电势及电场。并利用数值模拟显示了在中心轴线上的电势分布和电场分布,图象显示在中心位置处电势最大随着离中心点距离的增大电势越来越小且电势是以中心点为对称点,在无穷远处电势为零;电场也是以中心点为对称点并在中心点处电场强度为零,远离中心点时电场强度逐渐增加达到最大值时电场强度随着离中心点距离的增加再逐渐减小,在无穷远处电场强度变为零,电场强度以中心点为对称点且方向相反。

In the rectangular coordinate system, we express the electric field intensity and different position electric field energy of the elliptical ring with positive electric charge in the central axis. And the matlab software simulates the arrangement of electric field intensity and different position electric field energy of the elliptical ring with positive electric charge in the central axis.
