We find that magnetic neutrino-electron scattering is unaffected by oscillations for vacuum mixing of Dirac neutrinos with only diagonal moments and for Majorana neutrinos with two flavors. For Mikheyev-Smirnov-Wolfenstein mixing, these cases are again obtained, though the effective moments can depend on the neutrino energy. Thus, e.g., the magnetic moments measured with ν̅e from a reactor and νe from the Sun could be different. With minimal assumptions, we find a new limit on μν using the 825-d Super-Kamiokande solar neutrino data: |μν|≤1.5×10^-10 μB at 90% CL, comparable to the existing reactor limit.
