A global analysis of the solar neutrino data from all solar neutrino experiments combined with the KamLAND data is presented assuming that the solar neutrino deficit is due to the matter-enhanced spin-flavour precession effect. We used two types of magnetic field profiles throughout the entire Sun: Wood-Saxon shape and the Gaussian shape. We showed that for Dirac neutrinos, the allowed regions are independent of the magnetic field profiles for all of the magnetic moments that we used in this paper and the allowed region in the large mixing angle region shifted to the small mixing angle region as the value of muB is increased. We calculated the allowed regions at 95% CL. We also find a limit for the electron neutrino magnetic moment at 0.95 CL so that muB < 0.2 x 10(-7) mu(B)G for both magnetic field profiles at the 1sigma level.
