We have analyzed the implications of the energy of anisotropy of a ferromagnetic sphere suspended in a carrier fluid in its dynamics. The rotational viscosity, which for a particular geometry represents the increase of the viscosity of the system due to the presence of an external magnetic...

Having characterized the macroscopic behavior of a ferrofluid, giving expressions for the viscosities, as well as for the average of its magnetization, we analyze the dynamics of a non-magnetic particle (magnetic hole) suspended in a ferrofluid. Although the particles are not magnetic, when they...

In this paper we introduce some of the main ideas over transport phenomena in suspensions of ferromagnetic particles. In particular, an explicit calculation of the viscosities for spherical particles, based on a solution of the corresponding Smoluchowski equation, is carried out and compared...
