Abstract
For a highly-concentrated suspension of ferromagnetic particles characterized by dipolar interaction, when Brownian motion can be neglected, a model of a viscoelastic magnetizable continuum is developed. The constitutive equations and the kinetic coefficients are determined in the lubrication approximation on the basis of the periodic array model. In the problem of slow medium deformation in a constant magnetic field, for certain values of the determining parameters, an increase in the effective viscosity with decrease in the field strength due to the strong dipolar interaction of the particles is detected.
