Effect of the variation in permeability in a magnetic emulsion subjected to magnetic and hydrodynamic fields

Abstract

The effect the variation in permeability in water-based magnetic emulsions is studied under the action of a pulsed magnetic field and a hydrodynamic field generated when the cuvette containing a sample is rotated. Considerable (400–500%) variation in the permeability of the emulsion samples in the magnetic field is observed. It is shown that the optical effect of the variation in permeability wanes in the rotating cuvette
