Abstract: The study takes into account temperature dependent viscosity and thermal conductivity as well as induced magnetic field in describing the fluid flow .The partial differential equations governing the unsteady flow is transformed to a system of non-linear ordinary differential equations by similarity transformation. The transformed differential equations are solved by collocation method. The numerical results for the flow variables: velocity, temperature and concentration profiles are displayed graphically for several parameters and discussed in details. The effect of physical parameters such as: Skin friction, Nusselt number, Sherwood number and thermophoresis particle deposition are also tabulated. The results shows that the increasing values of positive variable viscosity parameter increases the velocity, temperature, concentration and decreases all the four stated physical parameters .For the decreasing values of negative variable viscosity parameter all the three flow variables decreases while all the physical parameters increases.
Keywords: boundary layer, variable viscosity, variable thermal conductivity, thermophoresis, unsteady flow.
