The variation of the terms in the generalized Ohm's law of the electric field across the current sheet near the largest X-line at t = 47 τ _c0 . The center of the current sheet is at x = 0. The lines represent the measured electric field E _y (solid, black), the induction component (dotted, red), the pressure component (dashed, green), the inertial component (dot-dashed, blue), and the total (pink, solid) of the three calculated electric field terms. The generalized Ohm's law mandates that the latter should equal the actual electric field, which is the case apart from fluctuations arising from numerical discreteness. The Ohm's law components are smoothed with a Gaussian kernel of standard deviation 0.33λ _p. It is clear that at the X-line, the pressure term dominates over the inertial term.
