The impurity has polarity and will be referred to as a {\\it dipole} impurity because it also has a direction and, consequently, changes its sign under the space inversion transform $x \\to -x$. Such a model is used to describe the inductively coupled to the Josephson transmission line qubit and the misaligned Abrikosov vortex that penetrates into the long Josephson junction. We derive the approximate equations of motion for the fluxon center of mass and its velocity.
