Generation of the electric current density spikes in a fast magnetoacoustic pulse. Perturbations of the absolute value of the radial velocity in the inwardly propagating pulse of compression, , are shown as a function of the radial coordinate r by the blue (thin) curves. The spikes of electric current density are shown by the red (thick) curves. The snapshots of the pulses (from right to left) correspond to the instants of time t = 0.5 s, t = 0.8 s and t = 1.1 s. The parameters are normalised by the maximum values at t = 1.4 s. The radial coordinate is measured in units of r1.
