The magnetic moment of a nucleus describes the strength and orientation of the magnetic field produced by the electric current density inside of the nucleus. The proton carries charge and both species of nucleon have non-zero gyromagnetic ratios, thus in the single-particle picture, the nuclear magnetic moment arises from the convection current associated with the motion of the protons and from the spin magnetization of the nucleons. Often times, however, the simple single-particle model fails to explain the experimental data. This is not necessarily surprising, however, since the potential between the protons and neutrons has an exchange component and therefore, can move charge throughout the nucleus. In Ref. [1], the effect of two-body currents was analyzed in QMC studies of the magnetic moments of light nuclei using both phenomenological and hybrid approaches. These studies indicated the need for many-nucleon currents in order to reach agreement with experimental data. In this section, I present a study of magnetic moments using a consistent the \(\chi \) EFT framework provided by the NV2+3 models.
