Abstract: | Images of fireballs on positively biased electrodes. (a) One‐sided fireball in an unmagnetized Ar plasma. (b) Spherical fireball concentric with small gridded electrode, B=0. (c) Fireball to a gridded electrode in the diverging magnetic field of a permanent magnet. (d) Neon fireball to a gridded electrode in the center of a mirror magnetic field between two permanent magnets. (e) Asymmetric fireball in a cusp magnetic field between two opposing permanent magnets. (f) Fireball elongated along the radial magnetic field lines of a cuspfield topology.
