The concept of Maxwell's displacement current is still not fully understood. In this paper, we measured the magnetic field between the plates of a charging capacitor using a magneto-optical method, which is generally explained to be produced by Maxwell's displacement current. We observed the asymmetric radial profile of the magnetic field between them, which could not be explained by using the displacement current. In contrast, it could be explained naturally, if we assumed that the magnetic field was produced by the practically existing conduction currents, which consist of the surface currents on the plates, the current in the charging wires connected to it and the return current connected to the electric power supply.

麦克斯韦位移电流的磁光测量

麦克斯韦位移电流的概念仍未完全理解。在本文中，我们使用磁光方法测量了充电电容器的极板之间的磁场，通常将其解释为由麦克斯韦位移电流产生。我们观察到它们之间磁场的不对称径向分布，这不能用位移电流来解释。相反，如果我们假设磁场是由实际上存在的传导电流产生的，则可以自然地进行解释，该传导电流包括极板上的表面电流，与之相连的充电线中的电流以及与之相连的返回电流。电源。
