Resumo

We considered a model medium of micron-sized magnetite particles and metal balls with a diameter of 1 mm in a viscous medium — glycerin. The processes of organization of this system in an external magnetic field as it increases are considered. The impact of shear vibrations on the processes of structure formation in the systems under study is also considered. The data obtained can serve as a basis for modeling the dynamics of disperse systems and expanding the understanding of their behavior and organization in magnetic fields and under mechanical influences.
