For a B2 V star model with a magnetic field of B = 1 kG for inward directed Lorentz force. Right panels: log N_i vs. cos (θ) (θ, co-latitudinal angle) for H II are plotted at two different profundities, log τ = 0.0 and log τ = -3.0. This ion shows a concentration towards the equatorial plane. Left panels: the stellar discs are represented in the corresponding depths in false colours.
