The variability of solar irradiance directly corresponds to
the solar activity and its Magnetic origin. We gave the exact solution of the
Virial- Theorem with taking into account the magnetic Energy’s , Rotational
Energy’s and kinetic Energy’s contributions too. The toroidal flow generates a
toroidal field from the poloidal components of the magnetic field as a result of
the differential rotation. So,the relevance for the solar dynamo is obvios. We
have applied our results to the meridional motion from Tacholin layer under
Convection Zone to surface latitudinal part. Calculated values of Energies (Gravitational,Magnetic,rotational)
in terms of distance from 0.4 R-1.0 R have been discussed.
