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.

恒定磁场中磁流体电导率的各向异性

摘要

在外部磁场中研究了油酸稳定的煤油上磁流体（MF）的电导率。电场和磁场以不同角度交叉时的电流-电压特性分析表明，磁性流体的电导率发生了变化。在相同的场定向情况下，电导率最大，而对于正交场定向则电导率最小。电极表面结构变化的研究表明，接触表面过程对电导率各向异性有重要贡献。
