The toroidal magnetic field plays a more important role in the early phases of the accretion process until the perturbed configuration finds a new equilibrium or disappears because of the runaway instability. We showed that additional perturbations in the vertical direction can lead to relativistic outflows if the perturbations are strong enough so that the mass could get far from the equatorial plane
