Angle between the electric field and the poloidal magnetic field, χ_EB, along the boundary streamline. At r_η = 100 r_S where the resistivity is switched on, the electric potential gradient starts to increase along the off-axis streamlines. This generates an electric field component along the streamlines and consequently the configuration of the electric field is affected. Past 10³ r_S, the gradient of Ω along the magnetic flux lines has become negligible. The electric potential gradient along the flux lines dies out and so the electric field becomes again perpendicular to the poloidal magnetic field.
