  Newton's third law states that any action is countered by a reaction of equal
magnitude but opposite direction. The total force in a system not affected by
external forces is thus zero. However, according to the principles of
relativity, a signal cannot propagate at speeds exceeding the speed of light.
Hence the action and reaction cannot be generated at the same time due to the
relativity of simultaneity. Thus, the total force cannot be null at a given
time. In a previous paper \cite{MTAY1}, we have shown that Newt\-on'n third law
cannot strictly hold in a distributed system, where the different parts are at
a finite distance from each other. This is due to the finite speed of signal
propagation, which cannot exceed the speed of light in the vacuum. A specific
example of two current loops with time dependent currents demonstrated that the
summing of the total force in the system does not add up to zero. This analysis
led to the suggestion of a relativistic engine \cite{MTAY3,AY1}. As the system
is affected by a total force for a finite period, the system acquires
mechanical momentum and energy. Now the question then arises how can we
accommodate the law of momentum and energy conservation. The subject of
momentum conversation was discussed in \cite{MTAY4}, while preliminary results
regarding energy conservation were discussed in \cite{AY2,RY,RY2}. Previous
analysis relied on the fact that the bodies were macroscopically natural, which
means that the number of electrons and ions is equal in every volume element.
Here we relax this assumption and study charged bodies, thus analyzing the
consequences on a possible electric relativistic engine.
