| Term: | Solar dynamo |
| Definition: |
A model for explaining the generation of the solar magnetic field and the related observational features (mainly solar cycle, Sporer's law, Hale's law, Joy's law, polarity reversal). The global frame of this model is the interaction between a turbulent plasma in the convective zone (reciprocal generation of magnetic and electric fields) and the solar differential rotation (mutual transformation of meridional magnetic field into azimuthal magnetic field). |
