Abstract: The effect of magnetic field and a non-uniform temperature gradient on the Marangoni convection in a horizontal fluid layer, heated from below and cooled from above with a constantheat flux was investigated. A linear stability analysis was performed to undertake a detailed investigation. The influence of various parameters on the onset of convection was analyzed. Six non-uniform basic temperature profiles were considered and some general conclusions about their destabilizing effects were presented.
