  Critical analyses of well-known methods of derivation of kinetic and
hydrodynamic equations is presented. Another method of derivation of kinetic
and hydrodynamic equations from classic mechanics is described. It is shown
that equations of classic hydrodynamics can be derived directly from
microscopic picture of motion, without using of kinetic equations as an
intermediate step. New method of derivation of equation of macroscopic motion
includes explicit averaging of microscopic motion on infinitesimally small
piece of medium. This averaging leads to presence of electric dipole, magnetic
dipole, and higher moments along with the charge density and the current
density in hydrodynamic equations. The method under consideration allows to
derive equations of evolution for new quantities.
