N2 - We consider the precession of an isolated curved solitary vortex line around a thin wire inside a coaxial cylindrical container, an experiment which has recently been done in superfluid3He-B. The analysis is performed in the localized induction approximation, based on the vortex-line tension concept, as well as in a model, in which some non-local corrections from interactions between distant parts of the vortex line have been taken into account. By minimization of the energy in the rotating frame, where the vortex configuration corresponds to the ground state, the boundary condition has been derived for the point where the vortex line disconnects from the wire. Accuracies of the local and the nonlocal approaches are compared.
