Which means that we need to multiply this equation by N, the number of loops in the coil.

这意味着我们需要将这个 等式乘以线圈中的回路数 N。

The voltage in the secondary coil divided by the voltage in the primary coil is equal to the number of loops in the secondary coil divided by the number of loops in the primary coil.

次级线圈中的电压除以初级线圈中的电压等于次级线圈中的回路数除以线圈数 初级线圈中的回路。

So if you want to know the total emf in the coil, you calculate the emf for one loop of wire, then multiply it by the number of loops in the coil, or N.

因此，如果您想知道线圈中的总电动势，您可以计算一圈电线的电动势，然后将其乘以线圈中的圈数或 N。

Faraday's law, which we talked about last time, says that the emf – or voltage – in each coil is equal to the number of loops in the coil, times the change in magnetic flux over time.

我们上次讨论过的法拉第定律说，每个线圈中的电动势（或电压）等于线圈中的回路数乘以磁通量随时间的变化。
