It is hypothesized that, during the collapse of the protosolar cloud, the magnetic field intensified. In the center of the just-formed, nonturbulent sun, the intensity of the magnetic field was 10,000 to 1 million G. If the sun passed through a stage of turbulent convection, only the field generated by dynamo action would remain. The poloidal magnetic field at this stage could reach 1000-1,000,000 G, but the intensity would decrease to 10-1 G during the decay of turbulent convection. The toroidal magnetic field would remain at 1000-1,000,000 G. It is possible that nonuniform rotation of the radiative region is related to distortions in the angular velocity in the internal convective zone due to magnetic tension.
