  Sterile neutrinos that couple to the Standard Model via the neutrino magnetic
dipole portals have been extensively studied at various experiments. In this
work, we scrutinize these interactions for sterile neutrinos in the mass range
of $\unit[0.1]{}-\unit[50]{MeV}$ through the nuclear and electron recoils at
various neutrino scattering experiments. For the $e$-flavor specific dipole
portal, we demonstrate that Dresden-II can provide leading constraints for $m_N
\lesssim \unit[0.5]{MeV}$, setting aside currently unresolved theoretical
uncertainties. For the $\mu$-flavor case, we show that the COHERENT experiment
can probe a unique parameter region for $m_N$ in the range of
$\unit[10]{}-\unit[40]{MeV}$ with the full dataset collected by the CsI[Na]
scintillation detector, including both the energy and timing structure of the
neutrino beam. We also present limits on the parameter regions of the
$\tau$-flavor dipole portal using measurements of the solar neutrino flux from
dark matter direct detection experiments.
