In the paper, proceeding from the equations of physical vacuum deduced on the basis of laws of classical mechanics, formulas of a magnetic induction and electric and magnetic intensities fields of an element of a current are obtained. The law of bio-savar-laplas is deduced, updating of the ampere's law, taking place not only for parallel, but also for orthogonal currents is found. Occurrence of electromotive force, ampere's and lorentz's forces are explained from positions of classical mechanics. It is shown, that occurrence of electromotive force of induction in a conductor is local effect and depends on the conductor and on local fields of perturbations of physical vacuum in a vicinity of the conductor, but not on the square of the contour limited by the conductor.
