  We present new aspects of the electromagnetic field by introducting the
natural potentials. These natural potentials are suitable for constructing the
first order distortions of the metric tensor of Complex Relativity - the theory
combining the General Relativity with the electromagnetic equations. A
transition from antisymmetric tensors to the symmetric ones helps to define the
natural potentials; their form fits a system of the Dirac matrices and this
representation leads to distortion of the metric tensor.
  Our considerations have originated from the recent progresses in the
asymmetric continuum theories. One version of such theories assumes an
existence of the antisymmetric strain and stress fields; these fields originate
due to some kind of internal friction in a continuum medium which have elastic
bonds related to rotations of the particles.
