A simple model of the sun in the presence of different interior magnetic field configurations (purely poloidal field, a general magnetic field having both poloidal and toroidal components, and a toroidal field) has been computed. The effects of these three types of magnetic field on the luminosity, radius, and effective temperature have been calculated. It is found that, although there is a change in luminosity of the configuration, the change in effective solar temperature depends mainly on the change in radius. Further, it is found that it is the toroidal magnetic field component that tends to reduce the effective temperature of the sun. The possible effect of changes in the magnetic field profile during the period of presolar activity and postsolar activity is discussed.
