The magnetic lines of force don't exist , they are defined by scientists.
磁力线并不存在,它是由科学家所定义。
As is mentioned above, a strengthened field is created where the lines of force in the two magnetic fields are parallel and have the same direction.
如上所述,两个磁场的磁力线相互平行且方向相同时,就形成了一个加强磁常。
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.
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。
It has been suggested that birds can sense the magnetic lines of force stretching from the north to south magnetic poles of the earth, and so direct themselves.
有人认为,鸟类能觉察得出地球自北向南磁极的磁力线,因而能为自己导向。
In this paper a complete set of MHD equations was used to study the energy storage in the solar atmosphere by twisting the tube of magnetic lines of force at the base.
本文从完整的磁流体动力学方程组出发,研究太阳大气中磁力线管根部的扭转储存能量。
A changed particle moves along the lines of force of a magnetic field, spiraling as it goes.
带电粒子沿磁力线运动时就会发生回转。
Magnetic lines of force (or flux) can be set up by passing a large current of electricity through the component to be inspected, by use of a magnetizing yoke, and by use of a magnetizing coil.
用大电流通过被测部件并用磁轭和用磁化线圈可以产生磁力线(或磁流)。
Magnets will attract magnetic materials only where the lines of force enter or leave the magnet at the poles.
磁铁只有在磁极处(磁力线进入或离开磁铁的地方)才能吸引磁性材料。
