| 摘 要： | 用毕－萨定律计算了分布在圆平行板电容器极板上电流的磁场,从而证实了：１）在似稳条件下磁场完全是由传导电流产生的,“位移电流”的磁场为零;２）极板电流在电路容器内部产生的磁场很大,它极大地的削弱了馈线电流的磁场,使得电容器内部的磁场很小．

| Abstract: | By calculating the magnetic field of the current distributed on the Plates of a parallel plate capacitor by Biot-Savart's law,it is concludeel that:1)Under quasi-steady conditions,the magnetic field is produced wholely by the conductive current and the magnetic field of the "displacement current" is null;2) Within the capacitor,the magnetic field of the plate current is strong,and it capacitor becomes very weak. |
