It's also  interesting to note that the physics of magnetic fields deflecting moving electrons, called the  Lorentz Force, is the driving principle behind all electric motors, just with coils of wires  and different configurations of magnetic fields.

同样有趣的是, 磁场偏转移动电子的物理原理,称为洛伦兹力, 是所有电动机背后的驱动原理,只需线圈和不同配置的磁场即可。

洛伦兹力

由于磁场的影响,电子射束的移动路径呈圆形。电子经过的路径会有紫色光发射出来。这是因为电子与玻璃球内的气体分子碰撞而产生的现象。
亨德里克·劳仑兹
在这篇文章内,矢量与标量分别用粗体与斜体显示。例如,位置矢量通常用\mathbf{r}\,\!表示;而其大小则用r\,\!来表示。

在电动力学里,劳仑兹力(Lorentz force)是运动于电磁场的带电粒子所感受到的作用力。劳仑兹力是因荷兰物理学者亨德里克·劳仑兹而命名。根据劳仑兹力定律,劳仑兹力可以用方程序,称为劳仑兹力方程序,表达为

其中,\mathbf{F}是劳仑兹力,q是带电粒子的电荷量,\mathbf{E}是电场,\mathbf{v}是带电粒子的速度,\mathbf{B}是磁场。

劳仑兹力定律是一个基本公理,不是从别的理论推导出来的定律,而是由多次重复完成的实验所得到的同样的结果。

感受到电场的作用,正电荷会朝着电场的方向加速;但是感受到磁场的作用,按照右手定则,正电荷会朝着垂直于速度\mathbf{v}和磁场\mathbf{B}的方向弯曲(详细地说,假设右手的大拇指与\mathbf{v}同向,食指与\mathbf{B}同向,则中指会指向\mathbf{F}的方向)。

Lorentz force 洛伦兹力

Lorentz force F on a charged particle (of charge q) in motion (instantaneous velocity v). The E field and B field vary in space and time.
Lorentz force (per unit 3-volume) f on a continuous charge distribution (charge density ρ) in motion. The 3-current density J corresponds to the motion of the charge element dq in volume element dV and varies throughout the continuum.
Trajectory of a particle with a positive or negative charge q under the influence of a magnetic field B, which is directed perpendicularly out of the screen.Beam of electrons moving in a circle, due to the presence of a magnetic field. Purple light is emitted along the electron path, due to the electrons colliding with gas molecules in the bulb. A Teltron tube is used in this example.Charged particles experiencing the Lorentz force.

In physics, particularly in electromagnetism, the Lorentz force is the combination of electric and magnetic force on a point charge due to electromagnetic fields. If a particle of charge q moves with velocity v in the presence of an electric field E and a magnetic field B, then it will experience a force
