A magnetic flux rope is sort of like a slinky.

这种磁性通量绳有点像个弹弹圈。

So the magnetic flux through the second coil changes, which induces an emf.

因此，通过第二个线圈的磁通量会 发生变化，从而产生电动势。

Because, remember, the inductor opposes the change in current with its own changing magnetic flux.

因为，请记住，电感器通过其自身变化的磁通量来对抗电流的变化。

As the capacitor discharges, current runs through both wires, generating a changing magnetic flux, just like Ampere's Law says.

当电容器耗尽时，电流会穿过所有电线，并产生可变磁通量，正如安培定律所述。

This results in the overall magnetic flux being zero.

这导致一般磁通量为零。

But a changing magnetic flux is also induced between the two plates when there's no wire connecting the plates.

但是当没有电线连接板时，两个板之间的可变磁通量也是如此。

This means that the magnetic flux through the loops in the coil changes over time, which is what induces an emf.

这意味着通过线圈中的环路的磁通量会随着时间而变化，这就是感应电动势的原因。

So with this equation, you can see the connection between a changing magnetic flux and an induced electric field.

即使使用这个方程，您也可以看到变化的磁通量和感应电场之间的联系。

As the loop rotates, the changing magnetic flux induces a current in the loops of the coil.

当环旋转时，变化的 磁通量会在线圈的环中感应出电流。

Well, Lenz’s law says that the magnetic field generated by the induced current will be in the direction opposite the change magnetic flux.

嗯，楞次定律说，感应电流产生的磁场将与变化的磁通量的方向相反。

This therefore creates a change in magnetic flux and induces a current in the loop.

因此，这会产生 磁通量变化并在回路中感应出电流。

And the current generates a magnetic field that opposes this change in magnetic flux.

电流会产生一个磁场 来对抗磁通量的这种变化。

After all, if a changing magnetic flux produces an electric field, why is there not a complementary law saying the reverse?

毕竟，如果不断变化的磁通量会产生电场，为什么没有相反的互补定律呢？

Maxwell's second equation is also a form of Gauss's Law, only with magnetic flux instead of electric flux.

麦克斯韦第二方程也是高斯定律的一种形式，只是用磁通量代替了电通量。

And this relationship works the opposite way as well, with a changing magnetic flux inducing an emf that opposes the flux.

这种关系也以相反的方式起作用，变化的磁通量会产生与磁通量相反的电动势。

The magnetic flux through the loop changes, which induces an emf.

通过环路的磁通量发生变化， 从而产生电动势。

For example, with coils of wire, we know that when the current is changing, a magnetic flux is induced in the coil.

例如，对于线圈，我们知道当电流变化时，线圈中会感应出磁通量。

Today, you learned about magnetic flux, and how a change in magnetic flux can induce an emf in a loop or coil of wire.

今天，您了解了磁通量，以及磁通量的变化如何在线圈或线圈中产生电动势。

If the magnetic flux through a loop of wire decreases over time, the emf increases accordingly.

如果通过线圈的磁通量 随着时间的推移而减少，则电动势会相应增加。

Magnetic flux is essentially a measure of the magnetic field running through a loop of wire.

磁通量本质上是通过导线环运行的磁场的量度。
