(color online) (a) Equilibrated voltage vs time responses of the sample contained centered slit (solid line) and off-centered one (dashed line) for and . Panels~1–4 [(a)–(d)] show the snapshots of magnetic field profile at times in V-Av pair dynamical process for the centered (off-centered) case. (b) Cross sections of magnetic field profile at for the centered case at time intervals indicated in the V–t curves.
