R. Hull is 100% correct.  The experimental apparatus used to measure  
coulombic force electrodynamically is an EM measurement rather than an 
electrostatic measurement.  It measures the force between two parallel 
wires as opposing current current flows in the wires and relates this 
force to electrons "flowing" in the wires.  The force of interaction in 
the wires is not a Coulombic force since neither wire has a net charge; 
it's totally an electromagnetic force.
