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