Anisotropy of magnetic fluid conductivity in constant magnetic fields

Abstract

The electrical conduction of a magnetic fluid (MF) on kerosene, stabilized by oleic acid, is investigated in an external magnetic field. The analysis of the current-voltage characteristics with electric and magnetic fields crossed at different angles showed a change in the conductivity of the magnetic fluid. In the case of the same orientation of the fields, the conductivity is maximal, while it is minimal for the orthogonal field orientation. The study of changes in the surface structure of the electrodes showed that the contact surface processes make a significant contribution to the conductivity anisotropy
