Up to now we have investigated the interaction of of our central droplet with a single dipole along the z-axis. To come to a more realistic scenario, we use a second coarse graining step: We assume that the environment outside the central droplet consists of dipoles with average dipole moment µ 0 as defined in Equ. . The central dipole µ c interacts with the surrounding dipoles µ s,i via dipole-dipole interaction. While perfectly aligned dipoles at a distance R close to each other show an interaction energy that scales like
