  Neutral particles are notoriously difficult to observe through
electromagnetic interactions. As a result, they naturally elude detection in
most collider detectors. In this paper, we point out that neutral particles
that interact through a dipole interaction can nevertheless be detected in
far-forward detectors designed to search for long-lived particles (LLPs). In
contrast to previous analyses that focused on neutral particles with elastic
interactions, we consider inelastic interactions. This naturally leads to LLPs,
and we demonstrate that FASER (and future experiments at the Forward Physics
Facility) will be able to probe substantial regions of the associated parameter
space. In particular, we find that FASER is capable of probing the region of
parameter space wherein thermal freeze-out gives rise to an $\mathcal{O}$(GeV)
dark-matter candidate with the appropriate relic abundance, as well as regions
of parameter space that are difficult to probe at fixed-target experiments.
FASER and its successor experiments may therefore play a critical role in the
discovery of such a dark-matter candidate.
