Abstract: 

A linear stability analysis is carried out to discuss the effects of horizontal magnetic field and horizontal rotation on thermal instability problem of a couple-stress fluid through a Brinkman porous medium. After employing normal mode method on the dimensionless linearized perturbation equations, it is noted that for the stationary state, Taylor number TA promotes stabilization, whereas medium porosityI hastens the onset of convection. The medium permeability P, magnetic field Q, couple-stress ? and Darcy-Brinkman parameter DA play dual role in determining the stability/instability of the system under certain restrictions.
Also, the sufficient conditions responsible for the non-existence of overstability are gained and the principle of exchange of stabilities holds good for a magneto-rotary system.
