The dynamics of structuring and light transmission in response to a transverse magnetic field applied to a gravitationally stratified layer of a ferromagnetic suspension is studied numerically and experimentally. The results obtained have been used to substantiate and implement in practice a magnetooptical method of measuring the fluid viscosity in thin films. This method is employed to investigate the viscosity kinetics of a polymer solution in a drying film.
