We report new bounds on electromagnetic properties of the muon neutrin
o obtained from a study of neutrino-electron scattering. The results a
re based on the analysis of differential cross section data collected
with the CHARM II detector. The 90% C.L. limit on the magnetic moment
of the muon-neutrino mu(nu mu) < 3 . 10(-9) mu(B) confirms limits obta
ined at much lower energies. The limit on the anomalous charge radius
of the muon neutrino \[r(2)]anom\ < 6.0 . 10(-33) cm(2) improves earli
er results by nearly a factor three.
