Item Langevin equations for suspended magnetic particles drifting under the Magnus force(Sumy State University, 2017) Pedchenko, B.O.; Yermolenko, A.S.; Denisov, Stanislav Ivanovych; Денисов, Станіслав Іванович; Денисов, Станислав ИвановичThe Magnus effect, i.e., dependence of the trajectory of a body on its rotation, is widely used in sport, science and technical applications. Recently we have shown [1, 2] that due to the Magnus force the single-domain ferromagnetic particles, which are suspended in a viscous fluid and subjected to a harmonic driving force and a non-uniformly rotating magnetic field, can perform drift in a preferred direction. This result has been obtained within the deterministic approach when thermal fluctuations, leading to translational and rotational Brownian motion of particles, are ignored. Our estimations show [2] that it is possible for relatively large particles (> 102 nm). Therefore, to study the drift phenomenon for smaller particles, it is necessary to account for these fluctuations in basic equations.
