... will not lead to change of the second term in the formula 2 it turns out with the first term a little bit more difficultly moving electron will perceive a potential field not how it was in a statics that it to define it is necessary to pass in the mobile system of coordinates connected with the electron we already know that the scalar potential enters as a component of the four-vector which is looking like and at transition to mobile system of coordinates will be transformed as time component ct in lorentz transformations 8 for scalar potential it will look so 9 where scalar product v2a in view of that other components of velocity v2 will not give the contribution to last term is used considering that for small velocity 1 from 9 is received for moving electron 10 according to the formula 2 with regard to movement electron and with use 10 it is had 11 last term in 11 we shall transform under the known formula of the vector analysis 12 where a and b any two vectors applying this formula to scalar product v2a we consider that derivatives on coordinates do not act on components of velocity v2 and as a result it turns out 13 the equation of movement of a particle in an electromagnetic field on which force operates will enter in the form of 14 we see that force f consists of two essentially various parts the first part the first and second members in the right part does not depend on velocity of a particle the second part the third member depends on this velocity force is proportional to value of velocity and perpendicular to it on character of action of electromagnetic force on its moving particle have conditionally divided into an electric part force which can impart energy to a particle and a magnetic part force which does not make work above a separate moving particle as it is always perpendicular to velocity of a particle such division of forces and fields has arisen historically even before creation of the electromagnetic theory that is to external attributes of display of forces lorentz force for the description of a magnetic field the vector is used 15 and the electric field is defined under the formula 2 now there is an opportunity to write the...
