What is the fine-grained topic of the following text: This work investigates mainly the magnetic field and the thermophoresis effects on the heat and mass transfer in steady laminar boundary layer flow of an incompressible viscous micropolar fluid over a moving vertical and permeable plate subjected to a magnetic field without neglecting the resulting dissipation. Only return the topic.
Effects of magnetic field and thermophoresis on heat and mass transfer in micropolar fluid flow over a moving vertical permeable plate.
