A numerical and similarity investigation of steady, viscous and incompressible boundary layer flow and heat transfer of a biomagnetic fluid over a linearly stretching sheet in the presence of an applied magnetic field due to a magnetic dipole is investigated. The density variation due to buoyancy effects is incorporated into account in the momentum equation. It is assumed that the applied magnetic field is sufficiently strong to saturate the ferrofluid and the variation of magnetization with temperature can be approximated by a function of temperature difference. Employing similarity variables the governing partial differential equations (mass momentum and energy conservation) of the flow are transformed into a set of ordinary differential equations. The resulting nonlineardifferential equations are solved numerically by applying an efficient numerical technique based on the common finite difference method with central differencing, subject to physically appropriate boundary conditions.
