所有磁场线圈请烘干和上漆。

All the field coils should be dried and varnished.

磁场线圈短路引起的过热，要更换磁场线圈。

If it is caused by the short circuit of the coil in magnetic field, change another coil.

一种为双边纵向磁场线圈，而另一种为单边纵向磁场线圈。

One has a double- sided coiled axial magnetic field and the other has a single-sided coiled axial magnetic field.

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。

For example, one of the experiments we do is measure the magnetic field of current coil, and after we do the experiment, we all have a passive visualization that shows the same experimental set-up, except we add to that.

比如，我们做的一个实验就是,测量电线圈的磁场，在我们做完实验之后，我们都感受到了一个直观化的过程,它展现了同样的实验过程，只是那是我们加的。
