MAGNETIC-FIELD TRANSFER IN SOLAR CONVECTIVE ZONE

The large-scale azimuth magnetic field is pumping to the bottom of the solar convective zone due to the diamagnetic action of turbulent conductive fluids. When the field at the bottom is of about 103G, an equilibrium is established between diamagnetic pumping and buoyancy. If, in addition to the density gradient, an additional anisotropy exists (for instance, due to rotation), another mechanism of the magnetic field transfer appears, the efficiency of which greatly depends on the magnitude of the anistropy parameter. © 1978 D.
