Abstract
The equations of magnetization for magnetic fluids with transformed microstructure have been investigated. Two parameters: effective field parameter and the average number of particles in aggregate have been used for describing of the processes of a structurization (association and dissociation of magnetic particle aggregates). The equilibrial dependences of these parameters on magnetization have been found under fixed temperature and density of fluid. The forms of magnetization curves have been studied depending on the values of coefficients contained in the phenomenological equations for pointed parameters. The obtained results have been compared with well-known experimental data. Figs 6, refs. 12.
