Detailed explanation-1: -The magnetic field at an average place on the Sun is around 1 Gauss, about twice as strong as the average field on the surface of Earth (around 0.5 Gauss).
Detailed explanation-2: -The magnetic field on the solar surface is very inhomogeneous. The strongest magnetic field regions are in sunspots, reaching field strengths of B =2000–3000 G.
Detailed explanation-3: -How does the sun’s radiative zone compare with the convective zone? The radiative zone is hotter and closer to the sun’s core.
Detailed explanation-4: -The source of the surface magnetism in the Sun lies in the convection zone, the layer of the solar interior just below the photosphere. The magnetic fields underlying stellar activity arise from some combination of convective flows and stellar rotation.
