FERREIRA, G. F. Leal. The equations of the quasi-steady states and an alternative view of the electromagnetic induction.* Rev. Bras. Ensino Fís.* [online]. 2001, vol.23, n.4, pp. 395-400. ISSN 1806-9126. http://dx.doi.org/10.1590/S0102-47442001000400006.

The equations of the quasi-steady states, for the fields and the potentials, covering electrostatics, magnetostatics and the Faraday Induction Law, are given. They are correct to the order of *v*^{2} = *c*^{2} and *wr* = *c*^{2}; *v* and *w* being the typical velocity and acceleration of the charges, *c* the speed of light and *r* the distance to a given point . This last fact allow us to obtain, in this approximation, the electric field of a moving charge, which corrects the Coulomb field by terms depending on the velocity and acceleration of the charge. Then, it may be shown, as done previously by Ritz and O Rahilly, that electromagnetic induction may be attributed to the acceleration of the charges of the inducting circuit, thus ensuing an alternative view of this interaction, usually attributed to flux variation enclosed by the circuit.
