The effect of a vertical magnetic field on the onset of convection in an electrically conducting nanofluid layer heated from below is investigated using the linear stability theory and the Buongiorno's mathematical model. In this investigation, we consider that the nanofluid is Newtonian and confined in a porous medium. The eigenvalue problem obtained is solved numerically for rigid-rigid boundaries using the Chebyshev-Gauss-Lobatto method.
