1.1.4.3.1. Symmetry of an electric field

| top | pdf |

Considered as an effect, an electric field may have been produced by two circular coaxial electrodes, the first one carrying positive electric charges, the other one negative charges (Fig. 1.1.4.1[link]). The cause possesses an axis of revolution and an infinity of mirrors parallel to it, [A_{\infty }\infty M]. Considered as a cause, the electric field induces for instance the motion of a spherical electric charge parallel to itself. The associated symmetry is the same in each case, and the symmetry of the electric field is identical to that of a force, [A_{\infty }\infty M]. The electric polarization or the electric displacement have the same symmetry.
