Magnetic field distribution produced by displacement current in charging circular parallel plate condenser

应用磁场矢势的概念讨论了充电圆形平行板电容器中的位移电流所产生的磁场分布 .由结果可知 ,其任一点磁感应强度的大小与离中心轴的距离之间不是简单的正比或反比关系 ,而是一种较复杂的函数关系 .

The magnetic field distribution produced by displacement current in charging circular parallel plate condenser is discussed by using the concept of magnetic potential. And it is proved that for any point the relation between the magnetic induction intensity B and the distance r, which is from a point to the condenser's centre, is not in direct ratio or inverse ratio, but is a complicated functional relation. In the sametime, the B of any point varies with the distance between the two plates and the point's height.
