2-D simulations of magnetogranulation provide evidence of a close connection between the magnetic field and nonstationary thermal convection. Fragmentation of large granules can lead to the formation of compact nearly vertical magnetic tubes from a weaker horizontal field. Conversely, the dissolution of granules can lead to a merging of magnetic elements and either to field cancellation (leading to the transformation of strong vertical field to its weaker horizontal state) or to the formation of broader and stronger magnetic structures.
