【内容简析】楞次定律是电磁学中的重要规律之一.楞次定律不是简单反映感应电流方向和磁通量增大或减小的直接关系,而是反映感应电流的磁场和引起感应电流的磁通量变化的关系,
【Content analysis】 Lenz’s law is one of the important laws in electromagnetism.Renkel’s law does not simply reflect the direct relationship between the direction of the induced current and the magnetic flux increases or decreases, but reflects the magnetic field induced current and induced current The relationship between changes in magnetic flux,
