  We calculate the magnetic moment of Dirac type of neutrinos in hot and dense
background for different ranges of temperature and chemical potential. The
properties of neutrinos are studied in the strong magnetic field where the
chemical potential of particles is high enough to have more particles than the
antiparticles. We show that in this situation, Weyl neutrino seems to explain
the neutrino coupling with the magnetic field due to its effective mass which
can couple with the magnetic field directly. We also investigate the
electromagnetic properties of Weyl neutrino due to its effective mass developed
in the strong magnetic field.
