Muromskii, Yu. Sergeev] The propagation of one-dimensional vertical perturbations of the magnetic particle concentration in a liquid-particle or gas-particle disperse medium in an external uniform magnetic field, oriented parallel or antiparallel to the force of gravity, is considered. The propagation of linear disturbances is analyzed. Linear stability criteria for layers of magnetized particles fluidized with a gas or liquid are found. The propagation of nonlinear long (kinematic) concentration waves in a medium containing dispersed magnetized particles is investigated. It is shown that in the kinematic wave approximation the propagation of the nonlinear concentration perturbations can be described by the Burgers equation. The formation of regions with a sharp change in concentration ("shock” fronts) is analyzed. The structure of the shock front, in particular its width, is found. It is shown that a magnetic field leads to broadening of the shock front, thus preventing the formation of concentration discontinuities and hence leading to the "smearing” of the boundaries of the inhomogeneities formed in the fluidized bed. This provides a basis for a qualitative explanation of the stabilization of developed nonuniform fluidized beds of magnetic particles in a magnetic field.
