On the Electrical Interaction as an Elastic Coupling Through the Flux Lines

By using the elastic coupling through the field lines, we present a new theoretical treatment of the electrical interaction. We consider both static and oscillatory fields. The obtained results show that the static interaction energy is in reverse proportion with respect to the distance between the centers of the two bodies whereas the oscillatory interaction energy contains two terms: one which is in reverse proportion with respect to the third power of this distance and the other which is in reverse proportion with this distance. The latter term appears because of retardation. An attraction between the two charged particles of the same sign may appear if the oscillatory energy of interaction is larger than the static energy of interaction. This is the case of the electron pairs in superconductors.
