Anisotropy of magnetic emulsions induced by magnetic and electric fields

TL;DR

This paper investigates how simultaneous electric and magnetic fields induce anisotropy in magnetic emulsions, affecting their conductivity and permeability tensors, with both theoretical modeling and experimental verification.

Contribution

It provides a theoretical framework and experimental validation for the anisotropic behavior of magnetic emulsions under combined electric and magnetic fields.

Findings

Anisotropy causes electric conductivity and magnetic permeability to become tensors.

Theoretical predictions match experimental measurements.

Electric and magnetic field intensities influence emulsion properties.

Abstract

The anisotropy of magnetic emulsions induced by simultaneously acting electric and magnetic fields is theoretically and experimentally investigated. Due to the anisotropy, the electric conductivity and magnetic permeability of a magnetic emulsion are no longer scalar coefficients, but are tensors. The electric conductivity and magnetic permeability tensors of sufficiently diluted emulsions in sufficiently weak electric and magnetic fields are found as functions of the electric and magnetic intensity vectors. The theoretically predicted induced anisotropy was verified experimentally. The experimental data are analyzed and compared with theoretical predictions. The results of the analysis and comparison are discussed.
