The magnetic field is self-consistently generated by the convective motions beneath the surface. Above the convection zone, we include a polytropic layer that extends to 1.6 solar radii. The temperature increases in this region to $\\approx8$ times the value at the surface, corresponding to $\\approx1.2$ times the value at the bottom of the spherical shell. We associate this region with the solar corona.
