Sammanfattning:The influence of electric fields on the magnetic susceptibility of magnetic colloids of different types was investigated. Dependences of the dynamic magnetic susceptibility of a kerosene-based homogeneous magnetic colloid on the intensity of the applied constant electric field were studied. Some features of such dependences were found at the additional impact of a constant magnetic field. The magnetic susceptibility of a magnetic colloid with a well-developed system of microsized droplet aggregates was also investigated under the action of a constant electric field as well as of an alternating electric field. Moreover, similar studies were carried out for a magnetic emulsion produced by emulsifying a kerosene-in-oil-based magnetic colloid. The peculiarities of the susceptibility of the considered systems were determined by structural changes which were observed and analyzed by optical microscopy. The results obtained were validated, and qualitative agreement between the experimentally obtained dependences and those calculated theoretically based on the models used was shown.
