Convective cells are excited externally in a fully ionized magnetized plasma, and their space-time evolution is investigated by two-dimensional potential measurements. A positive cell is excited externally in the ''scrape-off'' layer of a plasma column produced by surface ionization. Its interaction with the main plasma produces a new cell with negative polarity. The two cells propagate close to each other and interact only through a mutual perturbation of orbits.
