  We present an analysis of the solar neutrino data assuming the deficit of
solar neutrinos to be originated from the interaction of their transition
magnetic moments with the solar magnetic field. We perform fits to the rates
only and global fits and consider separately the existing data prior to the
announcement of the SNO NC results, and present data. Predictions for the
Borexino experiment are also derived. The solar field profiles are taken both
in the radiation zone and core of the sun, and in the convective zone. The
latter are chosen so as to exhibit a rapid increase across the bottom of the
convective zone and a moderate decrease towards the surface. Regarding the
field profiles in the radiative zone and core, it is found that the data show a
preference for those cases in which a strong field rests at the solar centre
with a steep decrease thereafter. For these, the quality of the global fits is
as good as the one from the best oscillation solutions and the same as for the
convective zone profiles examined. It is also found that the $\chi^2$ of the
fits increases when the most recent data are considered, owing to the smaller
errors involved. This in turn provides more precise predictions for Borexino
than previous ones, thus resulting in a clearer possible distinction between
magnetic moment and the currently favoured oscillation solutions.
