Query: Simple model of skeletal matter composed of magnetized electrically
  conducting thin rods   A simple electrodynamic model for describing the behavior of a skeletal
matter composed of magnetized, electrically conducting thin rods (1D magnetic
dipoles) is proposed. It is aimed at modeling the self-assembling of a skeletal
matter from carbon nanotubes (or similar nanodust), as suggested for
interpreting the experimental data on the long-lived filamentary structures in
the high-current electric discharges. Here the capability of the model is
illustrated with the example of how a straight tubular skeleton, which is
composed of ~300 dipoles and carry circular electric current in its wall, may
be wrapped up by a distant pulsed electric current to make a toroid-like
structure.
