磁力线是人们想象出来的并不真实存在的线，看不见摸不着，但磁力却真实存在（如：微波）,你只能靠想象它存在而在脑海或纸上绘出他的样子才能直观又形象的描述并研究它·那么切割磁感线说形象点就是用根棍子去切一根看不见绳子，你可以垂直于绳子横着切，也可以不垂直于绳子斜着切，只要你能切到的切法都算切割磁力线，当然这里的棍子指的是可导电的导体作成的一切物体。
指出了在磁场中做变速切割磁力线（线）运动的导体（不闭合）中有电流存在，讨论了其运动加速度。
The existence of electric current in the conductor(not closed)which is cut-ting the magnetic lines of force(B-lines) variably in the magnetic field is pointed out, and the acceleration is discussed.
不过此转子转动速度没有磁场变换之速度高，否则磁力线将不能为铜棒所切割。
However, the speed of the rotor rotation speed did not change the high magnetic field, or magnetic line of force will not be able to cut the copper.
假如住在方向不正的套宅，磁力线必然是斜着切割你的身体，虽然不见得有什么大碍，但总不及前者好。
If live in direction, cover frame-uply curtilage, lines of force is necessarily sideways cut your body, although what not likely has to hinder greatly, but always not as good as former good.
