Abstract

Newton's third principle is the most improtant principle in Physics beacuse the violationof this principle implies the existence of a unique reference frame defined by the so-called luminiferous Ether. Since the Lorentz force does not follow Newton's third principle, the violation of this principle has consequences which can be tested experimentally, namely a pair of charged particles at rest in the Earth reference frame  can set itself in motion and accelerate its center of mass without external help provided one of them has an initial relative velocity with respect to the other. We have designed  an experiment with a capacitor charged with a high voltage in order to show the existence of this effect.
