A boundary layer analysis has been presented to study heat transfer with the effects of temperature dependent viscosity and thermal conductivity in the laminar, viscous, incompressible, electrically conducting, micropolar fluid past a continuously moving plate in the presence of a transverse magnetic field. The governing equations are transformed to dimensionless similarity boundary layer equations. Numerical solutions are given for the governing momentum, angular momentum and energy equations using the shooting method. The effects of the magnetic field parameter, the viscosity variation parameter, thermal conductivity variation parameter and micropolar parameter on the skin friction, wall couple stress and rate of heat transfer are discussed.
