That is we make animation file when you put the current to the coil of the field, getting established magnetic field.

即通过制作动画效果，当你将电流，输送到线圈上，形成磁场。

The power source used 14 power file effect transistor MOSFET in power transformer second order; all the combinations of twist-coil could construct 18 different second orders.

供电电源则将14只功率场效应晶体管MOSFET接入电源变压器次级，两绕组的全部组合可构成18个不同扎数的次级。
