Abstract

In the present article authors investigate the kinetics of magnetization of a liquid at rest in time-varying magnetic fields. The characteristic times of formation of the structural elements of the system are determined from relatively large volume of the investigated medium is due to the need for a sufficiently high-frequency front of the magnetic field pulse. The rise time of the pulse front must be appreciably smaller than the characteristic time of the magnetic relaxation process. The required difference in the characteristic times of the processes of field application and magnetic relaxation was achieved in the experiments by increasing the viscosity of the carrier of the dispersed medium. The dispersed phase of the suspension was R-10 iron carbonyl powder with multidomain spherical particles of diameter approximately 3. 5 mu m. Suspensions with volume content of the dispersed ferromagnetic phase equal to 0. 04, 0. 065, and 0. 09 were used.
