Abstract
Results of theoretical modelling of heat production in a dilute suspension of fiber ferromagnetic particles under the action of a linearly polarized oscillating magnetic field are reported. The particles are assumed to be placed in a Maxwell viscoelastic liquid, which, in the first approximation, models biological liquids. Two mechanisms of heat production, namely, the particle rotation in the liquid and its internal remagnetization are considered. The effect of the particle shape, its magnetic properties and rheological properties of the carrier liquid on the intensity of the heat production are studied. Figs 6, Refs 22.
