Nonlinear magneto convection is discussed with the introduction of turbulent eddy diffusivities in the representative eddy simulation of the turbulent motion. It is found that the turbulent magnetoconvection is characterized by the effective Rayleigh number of about 4 times the critical Rayleigh number and by the effective Nusselt number of about 2. The solar convection zone is modelled into several representative zones, of which each zone has a characteristic scale such as shown by granule, supergranule and global convection cell. In the kinematic regime (the Chandrasekhar number Q < 1), the flux tube formation or the intensification of the magnetic field into thinner tubes results in the field strength as strong as about five times the...
