  Chiral magnetic insulators manifest novel phases of matter where the sense of
rotation of the magnetization is associated with exotic transport phenomena.
Effective control of such phases and their dynamical evolution points to the
search and study of chiral fields like the Dzyaloshinskii-Moriya interaction.
Here we combine experiments, numerics, and theory to study a zig-zag dipolar
lattice as a model of an interface between magnetic in-plane layers with
perpendicular magnetization. The zig-zag lattice comprises two parallel
sublattices of dipoles with perpendicular easy plane of rotation. The dipolar
energy of the system is exactly separable into a sum of symmetric and
antisymmetric long-range exchange interactions between dipoles, where the
antisymmetric coupling generates a nonlocal Dzyaloshinskii-Moriya field which
stabilizes winding textures with the form of chiral solitons. The
Dzyaloshinskii-Moriya interaction acts as a vector potential or gauge field of
the magnetic current and gives rise to emergent magnetic and electric fields
that allow the manifestation of the magnetoelectric effect in the system.
