Abstract: In ferrofluids three components namely core, surfactant and carrier fluids coexist. Thermal convection in a multicomponent fluid has wide applications in industrial, ionospheric and geothermal systems. In this paper, the effect of magnetic fields along the vertical axis on a soret driven thermohaline convective instability in a ferrofluid saturating rotating porous medium has been examined using linear stability analysis. The infinitely spread fluid layer is assumed to be contained in between two free flat conducting boundaries. The exact solutions for stationary and oscillatory instabilities are obtained. It is found that the stationary instability is possible for Taylor numbers up to 100. When the values of Taylor number are greater than 100, the system is found to stabilize through oscillatory mode. The calculations made on this study are shown graphically.
