Abstract
The classical Yang-Mills equation of motion is numerically
investigated in the Lorentz gauge for a SU(2) gauge group.
The color-electric field of two point-like charges is studied
in the "empty'' vacuum and in a state with an instanton present.
The major effect for a fixed orientation of the instanton is
that the color-electric field lines are expelled or attracted
from the instanton region depending on the orientation of the
instanton. If over the orientations of the instanton is averaged,
this effect drops out. In this case of a random instanton orientation,
we find that the external color-electric field is expelled from the
instanton core. The origin of this effect is discussed.
