So the transformer core material is required to be the one with properties of low losses at high frequency, high dynamic permeability, high saturation induction and low remanence.
要求变压器铁芯具有低的高频损耗，高动态磁导率，高饱和磁感应强度和低的剩磁比。

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。

Eight core oceans heart high-frequency smoother and exquisite, low-frequency texture better, acoustic field have the greater ascension, triple frequency equilibrium.
