The physical movement of copper atoms in a wire is the measured drift current in a copper wire. This is in stark contrast to the conventional understanding of current as moving electrons. The drift velocity of copper atoms due to an impact force of current thru the wire is the same phenomenon as seen in electrolysis of fluid ions. Atomic mass change of a copper atom is quantified under external current stress. The meaning of field and flux is now clear with data from a real experiment.
