And the curl of the electric field will generate voltage between these two guys. 电场的旋度,在二者间产生了电压。
That one tells you about the curl of the electric field. 那个关于电场旋度的方程。
Let's look at div and curl of the electric field. 先看看电场的旋度和散度。
That generates a magnetic field that varies over time, so that causes dB by dt and that causes curl of the electric field. 这就产生了一个随时间变化的磁场,∂B/∂t等于电场的旋度。
