The effect of the magnetic field on the onset of thermal convection in a porous layer saturated by Jeffrey nanofluid is studied. Three distinct boundary conditions are considered to be free-free. rigid-rigid and rigid-free boundaries. The model used for Jeffrey nanofluid includes the effect of Brownian motion and thermophoresis. https://www.jmannino.com/great-pick-2023-Armada-Tantrum-Junior-Skis-w-Atomic-Colt-7-GW-Bindings-hot-grab/
