MAGNETIC PERMEABILITY OF MAGNETODIELECTRIC EMULSIONS IN THE ROTATING MAGNETIC FIELD
In the paper the novel soft magnetic composite medium is investigated. A magnetodielectric emulsion studied demonstrates the strong magnetic properties which are atypical for commonly known classical emulsions. The influence of a rotating magnetic field on the magnetic properties of an emulsion is investigated. It was shown that if the magnetic field rotation period less than the time of the shape relaxation of droplets of dispersed phase the droplets oblateness in the plane of field rotation is taking place. Such droplets deformation leads to the specific change in the macroscopic magnetic properties of an emulsion. The dependence of the magnetic permeability of an emulsion on the rotating magnetic field strength is studied. It is shown that the magnetic permeability of an emulsion can change by ~ 10 % under the action of the magnetic field. The theory of the magnetic properties of the magnetodielectric emulsions in the rotating magnetic field is developed; the theory is in the good agreement with the experimental data.
