Dynamics of Levitated Volume of the Composite Bidisperse Magnetic System

Magnetic fluids have become popular due to a special combination of properties and the ability to change their physical parameters, such as viscosity, sound speed, light transmission with a change in the external magnetic field. Under specific conditions, interaction between magnetic nanoparticles, the forming and decay of aggregation, and a variation in their physic characteristics take place to composite bidisperse magnetic system. We have developed an original method for measuring the viscoelastic parameters of magnetic fluid systems, and test it on different magnetic composite fluids include bidisperse systems. Examples with various physic properties are studied and the viscosity dependence on the magnetic fied is investigated. The structure of the bidisperse examples with magnetic particles affect the dynamics of sample subjected to oscillatory shifts and magnetoviscous effects.
