EN

A two-phase model of dynamical behavior of magnetic liquid influenced by constant magnetic field is considered. The model takes into account mutual interaction of clusters giving skeleton's stiffness and interaction of clusters with free liquid producing attenuation and dispersion of waves for transversally isotropic system. Rotational degrees of freedom are disregarded. Predictions of the model are discussed for variable amount of clusters and compared with experimental data for different magnetic fields.
