In a system with randomly moving elements, organization and self-organization processes may occur. This paper analyzes self-organization process in continuously moving domain structures system. Simulation of dynamic parameters of helical domains and comparison with experimental data has been performed. This article analyzes self-organization processes in continuously moving magnetic domain system. A phenomenological approach to description of dynamic parameters of helical domains is proposed. It is shown that at certain magnetic effect the dynamic parameters of helical domains exponentially depend on stepwise magnetic field amplitude. Of particular interest are spatially ordered structures, formed as a result of self-organization in inanimate objects. The paper identifies and interprets from phenomenological point of view some patterns of self-organization in magnetic media structure. An idea is developed that such dynamic characteristics of helical domains as «lifetime» and «waiting time» have exponential dependence on alternating magnetic field parameters. This idea was used to analyze the experimental data obtained on iron garnet crystals. As a result, adjusting parameters have been calculated which describe in the best way experimental dependences of dynamic characteristics of helical domains on the amplitude and frequency of exciting magnetic field.
