Abstract: | On the basis of statistical analysis, we derive expressions for the dynamic susceptibility, magnetization relaxation times,
and the effective rheological characteristics of a moderately concentrated homogeneous ferrocolloid consisting of identical
spherical ferroparticles suspended in a Newtonian liquid. The magnetic moment of a particle is assumed constant and rigidly
“frozen” into the body of the particle. We also estimate how the magnetodipole and hydrodynamic interactions of the particles
influence the effective dynamic properties of the ferrocolloid.
