In this paper, we present results of theoretical modeling of the rise of temperature for the unit of time in a dilute suspension of the fiber ferromagnetic particles under the action of the linearly polarized oscillating magnetic field. Two mechanisms of the heat production, namely the particle rotation in the liquid and its internal remagnetization are considered. We study effect of the particle shape, its magnetic properties and rheological properties of the carrier liquid on the rise of temperature for the unit of time by the particles.

Magnetorheological (MR) fluids are suspensions of micron sized ferromagnetic particles dispersed in varying proportions of a variety of non-ferromagnetic fluids. MR fluids exhibit rapid, reversible and significant changes in their rheological (mechanical) properties while subjected to an external magnetic field. In this paper, a double-plate magneto-rheological fluid (MRF) clutch with controllable torque output have been designed. Electromagnetic finite element analysis is used to optimize the design of the clutch by using the commercial FEA software ANSYS.
