The solar dynamo is a research area focused on understanding the physical mechanisms by which the Sun’s internal plasma motions generate and sustain its large-scale magnetic field. It integrates magnetohydrodynamics, turbulence, rotation, and convection to model the conversion of kinetic energy into magnetic energy via dynamo action, typically involving differential rotation (the Ω-effect) and helical turbulence (the α-effect). Research addresses the solar cycle, polarity reversals, flux-transport processes, and the role of tachocline shear and convection-zone dynamics, using analytical theory, numerical simulations, and helioseismic constraints to test and refine dynamo models.
