The value of a magnetic material core varies according to the frequency of operation.

核心价值一磁性材料根据不同的操作频率。

For low-frequency currents(up to about 15, 000 cycles per second)an iron core, called a magnetic circuit; is placed.

对于低频率电流（约15，000周秒以内），置有一个叫作磁路的铁心。

The high frequency transformer is designed by the AP method. The type of magnetic core, wire guage and the coiling method are computed by the AP method.

高频变压器设计部分通过面积乘积法算得变压器的磁芯型号、绕线规格和绕制方法。
