Abstract

In the article is developed the concept of scalarvector potential, based on the symmetrization of the equations of induction, during record of which is used the substantional derivative. The physical causes of molding of Lorentz force are examined. is shown that the dependence of the scalar potential of charge on the speed is the physical cause of Lorentz force. The examination of power interaction of the current carrying systems is carried out and it is shown that with the low speeds of charges the concept of scalar- vector potential gives the same results as the concept of magnetic field. It is shown that the Lorentz force is connected with the gradient of scalar potential. This potential form the charges, which move in the field of the vector potential of magnetic field, which, is in turn the consequence of the dependence of the scalar potential of charge on the speed.
