文摘

In this article, we investigate the field-driven motion of magnetic fluids (ferrofluids) in ferromagnetic nanowire under the influence of its own inertia. We establish the results in the framework of modified Landau-Lifschitz-Gilbert equation of micromagnetism which comprise the nonlinear dissipation factors like dry-friction and viscous. We delineate the motion in both the dynamical regimes namely the steady-state and the precessional. In the end, the physical significance of the obtained results is discussed with an aid of numerical analysis.
