As was previously shown (Kleeorin et al. 1990; Kleeorin & Rogachevskii 1994a), small-scale magnetohydrodynamic (MHD) turbulence results in modification of the Ampere law, by significantly reducing the elasticity of the magnetic field lines. As a result, the 'effective' magnetic pressure is reduced and may even reverse its sign. We show here that this modification can be related to a variety of phenomena observed in the Sun and in particular the following four are investigated: the 11-year variations of the solar radius, the torsional oscillations and the meridional flows, the solar short time oscillations and the large-scale magnetic flux ropes formation in convective zones of the Sun (as well as in stars and spiral galaxies).
