Parallel and perpendicular components of the electrical current at t = 80 s (upper two panels) and t = 160 s (lower two panels) in the same diagnostic plane as in Fig. 4. The enhancement in perpendicular current is located at the same place of the temperature maximum. The electrical current in the color bar is presented in units of J₀ = 1.54 × 10^-4   A/m². The spatial scale is given in units of L₀ = 500 km.
