A phenomenological model is proposed to describe the plasticity of soft magnetic elastomer composites under an external field. Along with high elasticity, internal dry friction is introduced whose origin is attributed to the dipole-dipole interaction of the embedded particles. Numerical estimates of the model parameters are obtained from comparison with the measurements performed on iron carbonyl dispersions in soft silicon-rubber matrices.
