ABSTRACT: The aim of this paper is to present numerical investigation on the magnetothermomechanical interaction between heated viscous incompressible ferrofluid and a cold wall in the presence of a spatially varying magnetic field. The two-dimensional parallel flow of a heated saturated ferrofluid along a surface, whose temperature increases linearly with distance from the leading edge, under the influence of the magnetic field due to two equally directed line currents which are perpendicular to the flow plane and equidistant from the wall is investigated. The influence of governing parameters corresponding to various physical conditions are analyzed. Numerical results are exhibited for the distributions of velocity and temperature, and the effect of the Prandtl number, the power law exponent and the ferrohydrodynamic interaction parameter is presented
