We investigate the effects of the transitional magnetic dipole type interactions of the active-to-heavy-neutrino associated with a new neutral gauge boson Z ′ on neutrino-nucleon scattering at the ForwArd Search ExpeRiment- ν (FASER ν ). We consider the neutral-current neutrino-nucleon scattering ( ν A → N A ′ , where A ′ denotes the disintegrated nuclei) as the production mechanism of the heavy neutrino N at FASER ν and estimate the sensitivity reach on the magnetic-type dipole coupling ω ν α for a range of heavy neutrino mass ( 1 GeV < M N < 70 GeV ). In this study, we consider three benchmark models, in which the heavy neutrino is coupled to L e , L μ or L τ doublet, respectively.
