Solar magnetic field strength correlates strongly with other solar activity, such as TSI and sunspot number. (skepticalscience.com)
We find that most of the solar cycle variation in the total solar irradiance can be accounted for by the absolute magnetic field strength on the solar disk, if fields associated with dark and bright regions are considered separately. (aanda.org)
