    ... and modeling of mechanisms of formation of field of forces is not always carried out this contributes certain uncertainty in the understanding of magnetic interactions between particles in the work the attempt is made to reveal the mechanism of magnetic interactions through reviewing of scattering of acoustic waves of physical vacuum as a quasielastic medium the reality of existence of physical vacuum as material medium is proved in works 1 2 thus in the beginning in an outcome of scattering of casual acoustic waves of physical vacuum by electrons is formed a spherical symmetrical coulomb field representing a stream of spherical longitudinal coulomb waves then at driving of electrons in physical vacuum at the expense of delay of spherical scattered waves and deforming a spherical symmetrical field the magnetic field as a secondary effect from a coulomb field is formed at acceleration of electrons occurs the transversal modulation of longitudinal coulomb waves with forming the transversal electromagnetic waves the magnetic field in the given model is calculated with the help of retarded lienard-wiechert potential under the laws of a classical wave mechanics and acoustics as shown in works 3 4 5 the considered model reduces in numerous interesting outcomes which completely will be agreed experimental dates introduction now it is considered that analytical expression for lorentz force is not deduced from maxwell equations or the special theory of relativity expression for this force is usual receive from lagrange equations for dynamics of a particle in which interaction lagrangian steals up in such kind that it corresponded to experiment therefore it is possible to believe that the finding of this force generally is not very simple having a preliminary set of the equations which have been considered by us it is possible to try to estimate character of interaction between particles moving with optional velocity thus it is possible to act in two ways in the beginning to find a kind of a field of the scattered waves from the first particle in view of its movement and then to find force of influence of these waves on the second particle or on the contrary the question on how the moving particle influences on motionless has been solved at a finding of retarded potential 15 33 1 on a moving particle this retarded potential obviously will influence a little differently as it is required to define thus the picture of the scattered waves of physical vacuum which was spherically symmetric in a static is deformed twice in the beginning due to movement of the first particle into physical vacuum and then due to movement of the second particle generally electromagnetic interaction between moving particles is very complex for an estimation of character of this force we shall consider the elementary case namely an example from magnetostatics i e interaction of one moving arbitrarily electron with an electric current or a cloud slowly moving electrons for simplification of calculations we shall consider that velocity of particles is small and therefore consequently some effects of delay of fields can be neglected interaction between moving particles conclusion of the basic equations the force acting on separate motionless electron from moving particles is defined by electric field intensity e according to the equation 2 where scalar potential and vector potential a are created electrons moving in a conductor now it is necessary to establish as intensity e will change in the event that separate electron will move with optional velocity v2 we shall begin with the second term namely we shall write a full derivative on time from vector a with regard to movement of electron 3 if in that area where electron is moving there are no extraneous charges and currents i e 0 and j 0 then from lorentz gauge 4 which has been deduced by us from the equation of a continuity 5 we receive 6 as a result for moving electron from 3 it is had 7 thus movement of electron with a velocity v2 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...

    ... the sa example you know for this reason his armored forces get name waffen-ss and supposed to be used as an army reserve and sometime to serve as concentration camps guards on rotation base only at that time waffenss at the beginning adolf hitler standard das grosse deutschland standard das reich and totenkopf and leibstandard were not super army as the world learned at the wwii the 1st battle experience of waffenss was in 1938 at france they did show of themselves as brave but completely out of military training soldiers wermacht was much better equipped and better trained that time the division adolf hitler the only ss men participated at france invasion destroyed catholic churches and did shot of few the uk s pows the 1st international crime committed by the ss men they did not show of themselves as battlefield soldiers himmler learned the lesson and shortly his armored forces became the best soldiers ever you know the price for his men army training himmler sold slave human labor for german industry for cheap and his organization bought any military supply by discounted prices and get priority to buy military supply even before wermacht waffenss became better equipped and better budgeted then wermacht but that was war time and really bad time to compete with wermacht generals for political power waffenss became army reserve till 1944 to 1940 waffenss got serious loses not bigger loses then wermacht did but that was significant for the ss organization the waffenss started to recruit foreigners the viking is the division recruited in belgium dutch etc southeast europe did follow never ever were national conflicts inside the ss at least between west european soldiers from the 1st training people learned everyone is an equal for the ss i saw the ss veteran from holland who was a commander of multinational units including german officers one of the most important requirement to people at the ss was a comradeship i specifically did a search for national conflicts in the ss i do not know about even single case the comradeship was one of the strongest feature of the elite german army as the waffenss used to be inside waffenss were georgia battalion armenia battalion azerbaijan battalion ukranian and even uzbek battalions all baltic republics gifted to the ss by legion russia was represented by vlasov s army i did not see any internal ss documents about the ss units from former ussr citizens normally commanders of all units were german officers but with time and with heavy loses everything was mixed around to make the distinguish between international ss troops into official names were included for one more word the standards with major aryan men received a word freiwilligen those units that contained a high percentage of non-germanic personnel carried the designation waffen- within their names that is probably why you decide waffenss is for non-germanic divisions only when you use official name like some -waffen-grenadier-division-ss means that division is mainly from non-germans you may use waffenss word to call all himmler armored forces and that is correct way to say waffenss was...
