In the first part of this work, a simulation program is employed to simulate the nanoparticle rearrangement for different particle concentrations and different magnetic field intensities. In the second part, the simulated particle distributions'' optical response is determined by means of a mixture law, which avoids typical huge computational times associated to this stage of the calculation. Experimental and simulated results with both parallel and perpendicular magnetic field orientations with respect to the incident light are compared. A significant correlation is obtained, which proves the usefulness of the proposed method in order to obtain the optical transmission evolution of a ferrofluid. info:eu-repo/grantAgreement/ES/DGA/E44-17R info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.409 2021 PHYSICS, APPLIED 61 / 161 = 0.379 2021 Q2 T2 0.717 2021 Acoustics and Ultrasonics 2021 Q1 Surfaces, Coatings and Films 2021 Q1 Electronic, Optical and Magnetic Materials 2021 Q1 5.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Martín, Juan Carlos Universidad de Zaragoza (orcid)0000-0002-8738-753X 2002 247 Universidad de Zaragoza Dpto.
