  We proceed with the construction of normalizable Dirac wave packets for
treating chiral oscillations in the presence of an external magnetic field.
Both chirality and helicity quantum numbers correspond to variables of
fundamental importance in the study of chiral interactions, in particular, in
the context of neutrino physics. In order to clarify a subtle aspect in the
confront of such concepts which, for massive particles, represent different
physical quantities, we are specifically interested in quantifying chiral
oscillations for a {\em fermionic} Dirac-{\em type} particle (neutrino)
non-minimally coupling with an external magnetic field {\boldmath$B$} by
solving the correspondent interacting Hamiltonian (Dirac) equation. The
viability of the intermediate wave packet treatment becomes clear when we
assume {\boldmath$B$} orthogonal/parallel to the direction of the propagating
particle.
