The viscous, two-dimensional, incompressible and laminar time dependent heat transfer flow through a ferromagnetic fluid is considered in this paper. Flow takes place in channel between two parallel flat plates under the influence of the permanent magnet or magnetic dipole located beyond the channel. It is assumed that there is no electric field effects and the variation in the magnetic field vector that could occur within the ferrofluid is negligible. This magneto-thermo-mechanical problem is governed by dimensionless equations. Results are obtained using standard computational fluid dynamics code FEMLAB with modifications to account for the magnetic term when needed.
