Laminar mixed convection flow of an incompressible, electrically conducting, viscous fluid with variable viscosity and variable thermal conductivity through two parallel horizontal walls under the influence of variable magnetic field is studied. Arrhenius model is used to express variable viscosity and thermal conductivity. In this model, the variable viscosity, and also the thermal conductivity decrease exponentially with temperature. The fluid is subjected to a constant pressure gradient and an external magnetic field perpendicular to the plates. The plates are maintained at different but constant temperatures. Approximation technique is used to obtain the solution of the coupled non-linear equations of the velocity field and the temperature distribution. The expressions for skin-friction and heat transfer rate are also derived. The effects of parameters of engineering importance on velocity field and temperature distribution are discussed graphically, while effects on skin-friction and rate of heat transfer are presented in tabular form and discussed.
