Abstract

In the present paper, we consider the possibility of interaction between geoneutrinos and the geomagnetic field, by adopting an approach based on the Dirac's equation with a non-minimal coupling that accounts for the magnetic interaction of the massive neutrinos. In our approach, we see that the magnetic interaction is controlled by a dimensionless parameter, $f\simeq 10^{-1}$, and we estimate the mean value of this interaction to be of the order of $10^{-14}\ MeV^{2}$.
