MOVEMENT OF A POINT STRUCTURAL PARTICLE I N ELECTRIC AND MAGNETIC STATIONARY FIELDS AND THE CLASSICAL ANALOGOUS OF SPIN

In the present paper, the motion of a neutral pointlike structural par ticle (PSP) in a Coulomb field is studied in the frame of the PSP theo ry, where a new classical analogous of spin is found. The particle is under the influence of an atractive short range potential of electroma gnetic nature due to its polarization in this field. The polarization of the PSP in crossed and constant electric and magnetic fields, and t he dependence of the drift velocity on the charge, are also studied.
