?电场线
用画电场线(electric line of force)的形式表示,电场线代表了正电荷移动的路径(其实在现实中正电荷是不会移动的,所以在这里只是用负电荷的相反方向代替)
An electriclineofforce is also a closed line; it too forms a loop and returns on itself.
电力线也是一条封闭线;它形成一个圈,返回原处。

Traveling-wave interaction and secondary magnetic field is generated electromagnetic force, which is a straight line to run the basic principles ofelectric motors.
行波磁场与次级相互作用便产生电磁推力,这就是直线电动机运行的基本原理。
