Abstract—The increase in light scattering during photolysis of benzophenone dispersions in polyelectrolyte
complexes on the basis of polyacrylic acid and cetyltrimethylammonium bromide was found to be strongly
affected by a magnetic field. These effects are one or two orders of magnitude stronger than the primary mag-
netic effects, which are measured by the influence of the field on the accumulation of the products formed dur-
ing photochemical reduction of the ketone. Analysis of light scattering spectra and the dependence of the mag-
netic effect on the sample properties and irradiation conditions shows that a magnetic field accelerates structural
transitions in micron-sized particles, thus increasing their refractive index.
