  While the evidence for dark matter continues to grow, the nature of the dark
matter remains a mystery. A dark $U(1)_D$ gauge theory can have a small kinetic
mixing with the visible photon which provides a portal to the dark sector.
Magnetic monopoles of the dark $U(1)_D$ can obtain small magnetic couplings to
our photon through this kinetic mixing. This coupling is only manifest below
the mass of the dark photon; at these scales the monopoles are bound together
by tubes of dark magnetic flux. These flux tubes can produce phase shifts in
Aharonov-Bohm type experiments. We outline how this scenario might be realized,
examine the existing constraints, and quantify the experimental sensitivity
required to detect magnetic dipole dark matter in this novel way.
