  Among the class of models with small mixing angles between sterile and active
neutrinos, we place constraints on the effective muon-to-sterile neutrino
magnetic and electric dipole transition moments from the combined MiniBooNE
results for the sterile neutrino mass range of $10\;\mathrm{MeV}<m_s<500\;
\mathrm{MeV}$. Our results are valid for models with CP-violating interactions
and for Dirac and Majorana sterile neutrinos. In addition, we show that such
dipole electromagnetic interactions cannot be the main source of the anomalous
events in the MiniBooNE experiment because they fail to reproduce the anomalous
event distribution as a function of polar angle. However, good agreement with
the anomalous event distribution in reconstructed energy can be achieved for
some values of magnetic and electric moments.
