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。
We can actually see spatially all the details in the field animated as you turn the current on and off.
我们能看到,所有细节的空间动画分布,就在你打开电流和切断的时候。
Self learners have also told us that they are OCW eager to come to OCW often in order to keep current and the latest thinking in their field.
自学者告诉我们,他们渴望每天经常浏览,以便查询他们领域的最新思想。
And when you turn the current off, the magnetic field collapses.
当你切断电流,电磁场就消失了。
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。
