The effect of temperature-dependent viscosity on the threshold of ferroconvective instability in a porous medium is studied using the Brinkman model. It is found that the stationary mode of instability is preferred to the oscillatory mode. The critical values of the magnetic Rayleigh number marking the onset of ferroconvection are obtained using the Galerkin technique. It is found that the effect of magnetization is to destabilize the system and so is the effect of temperature-dependent… CONTINUE READING
