The "theory of informatons" explains the electromagnetic interactions by the hypothesis that "e-information" is the substance of E.M. fields. The constituent element of that substance is called "an informaton". The theory starts from the idea that any material object manifests itself in space by the emission of informatons: granular mass and energy less entities rushing away with the speed of light and carrying information about the position, the velocity and the electrical status of the emitter. In this article the E.M. field in a point is characterized as the macroscopic manifestation of the presence of a cloud of informatons near that point; Maxwell's laws are mathematically deduced from the dynamics of the informatons; the electromagnetic interactions are explained as the effect of the trend of an electrically charged object to become blind for flows of e-information generated by other charged objects; and photons are identified as informatons carrying a quantum of energy, what helps us to understand the strange behaviour of light as described by QEM.
