  We calculate the relaxation of Brinkman-Smith mode via Leggett-Takagi
relaxation in the presence of an isolated vortex in superfluid 3He-B. The
calculation is based on an analytical solution of the order parameter far from
the vortex axis. We obtain an expression for the dissipated power per vortex
length as a function of the tipping angle of the magnetization and the
orientation of the static magnetic field with respect to the vortex.
