| Abstract(in English) | The electromagnetism taught at schools is usually based on the six equations published by J.C. Maxwell in 1864. There is another basic electromagnetic phenomenon called Lorentz’ force, which states that to a moving particle at velocity v in a magnetic field B feels an electric field expressed by the vector product v x B. The two theories are applied properly to practical problems but their mutual relations seem rarely presented. On the other hand the Lorentz’ force was derived quite naturally in the paper “On electric dynamics of moving bodies” by A.Einsten in 1905 based on the relativity principle. However, the given formula isβ.v x B, whereβ=√(1- (v/c)^2 ). v is the velocity of the moving particle, c is the speed of the light in vacuum. The author understood the Lorentz’s field is a relativistic phenomenon but had the doubt that the usual expression is only approximate that hold only for v/c << 1. The doubt is now cleared by deriving Lorentz formula from Maxwell’s equations directly and further study of the relativistic theory as herein reported. |
