We present a calculation of magnetic moments for selected spin-1 mesons using the techniques of lattice QCD. This is carried out by introducing a progressively small static magnetic field on the lattice and measuring the linear response of a hadron's mass shift. The calculations are done on 24{sup 4} quenched lattices using standard Wilson actions, with {beta}=6.0 and pion mass down to 500 MeV. The results are compared to those from the form factor method.
