  We consider Majorana neutrino conversions inside supernovae by taking into
account both flavor mixing and the neutrino magnetic moment. We study the
adiabaticity of various possible transitions between the neutrino states for
both normal and inverted hierarchy within the various solar neutrino problem
solutions. From the final mass spectrum within diffrent scenarios, we infer the
consequences of the various conversion effects on the neutronization peak, the
nature of final spectra, and the possible Earth matter effect on the final
fluxes. This enable us to check the sensibility of the SN neutrino flux on
magnetic moment interaction, and narrow down possible scenarios which depend
on: the mass spectrum normal or inverted, the solution of the solar neutrino
problem; and the value of MuxB.
