  We discuss $\nu - \gamma$ interactions in the presence of a homogeneous
magnetic field with energies less than pair production threshold. The neutrinos
are taken to be massless with only standard-model couplings. The magnetic field
fulfills the dual purpose of inducing an effective neutrino-photon vertexes and
of modifying the photon dispersion relation. Our conclusion is $\nu - \gamma$
interactions are too weak to be of importance for pulsar physics.
