摘要
本文针对只有高速情况下的相对论效应才是显著的这一认为,从两个具体实例出发,进行相对论分析处理,得到下述结论:低速条件下的相对论效应是重要的.磁场是在低速条件下电场的相对论效应.低速条件下的洛仑兹收缩毕竟是微乎其微的,磁场力在数量级上确实也比电场力小很多.通过分析比较,进一步说明了磁场力得以被观测和应用的原因.
Considering the idea that relativistic effectis notable only iu high speed motion while it can always be neg-1igibl. in low speed motion, this paper gives relativistic analy-sis by use of two examples and draws following conclusins: therelativistic effect of low speed motion is important and magne-tic field is not anythiog else but the relativistic effect of elec-tric field low speed condition, the Lorentz contraction at lowspeed condition is very small after all, the magnetic force issmaller of tbe order than electric force.The reasons are why themagnetic force can be obserred and applied further by analysisand comparison.
