  We present the detection of a magnetized dust ring (M0.8-0.2) in the Central
Molecular Zone (CMZ) of the Galactic Center. The results presented in this
paper utilize the first data release (DR1) of the Far-Infrared Polarimetric
Large Area CMZ Exploration (FIREPLACE) survey (i.e., FIREPLACE I; Butterfield
et al. 2023). The FIREPLACE survey is a 214 $\mu$m polarimetic survey of the
Galactic Center using the SOFIA/HAWC+ telescope. The M0.8-0.2 ring is a region
of gas and dust that has a circular morphology with a central depression. The
dust polarization in the M0.8-0.2 ring implies a curved magnetic field that
traces the ring-like structure of the cloud. We posit an interpretation in
which an expanding shell compresses and concentrates the ambient gas and
magnetic field. We argue that this compression results in the strengthening of
the magnetic field, as we infer from the observations toward the interior of
the ring.
