Abstract
The paper deals with an experimental study of the emulsion whose dispersion medium is a magnetic fluid, whereas the disperse phase is formed by water. It is demonstrated that chain aggregates are formed from the disperse phase drops under the action of an external magnetic field. The change of the emulsion microstructure affects its electrical properties. The emulsion specific electrical conductivity was measured. It was found that under relatively weak external magnetic fields the emulsion electrical conductivity may change several times. Figs 3, Refs 8.
