Abstract

When a thin horizontal layer of fluid is heated from below, convection starts after that the temperature difference between the lower and upper surfaces has reached a critical value. Two effects are responsible for this motion : buoyancy and variation of the surface tension with temperature ; the first effect is usually referred to as Rayleigh-Benard instability, the second as Marangoni instability. In the present work, we examine the role of the application of a vertical magnetic field on a thin horizontal electrically conducting fluid layer. Some particular effects will be i
