Normalized parallel component of the electric field. For each panel group, E ⋅ B (left panel blocks) and E ⋅ v (right panel blocks) are shown for different values of the diffusivity at t = 300 in a symmetric logarithmic scale. The parallel components are normalized with respect to the corresponding quantities. The left and right panels of each block show results computed with resistivity values of η = 10⁻³ and η = 10⁻², respectively.
