Contribution of the magnetic energy to the energy of field of a rotated charged conducting spheroid is calculated by a method which is not use operations both the volume integration of the magnetic energy density as the surface integration of the scalar product of the current density vector and the vector potential of field. The method may be interesting for person, studying the classical electrodynamics course.
