The viscosimetry method which is suitable for studying 
the kinetics of viscosity of a polymer solution in a drying film and 
is based on the measurement of the dynamics of light transmission 
of a two-layer system (excited by magnetic-field pulses and formed 
from sedimentation of noncolloidal ferromagnetic particles suspended 
in the fluid) has been substantiated. Optimum conditions for its implementation 
have been determined by computer modeling of the collective behavior 
of a system of particles.
