  We report the detection of the ordered alignment between the magnetic field
and kpc-scale bubbles in the nearby spiral galaxy, NGC\,628. Applying the
Velocity Gradient Technique (VGT) on CO spectroscopic data from the
ALMA-PHANGS, the magnetic field of NGC\,628 is measured at the scale of 191\,pc
($\sim$ 4\,$''$). The large-scale magnetic field is oriented parallel to the
spiral arms and curves around the galactic bubble structures in the
mid-infrared emission observed by the James Webb Space Telescope (JWST).
Twenty-one bubble structures have been identified at the edges of spiral arms
with scales over 300\,pc, which includes two kpc-scale structures. These
bubbles are caused by supernova remnants and prolonged star formation and are
similar to the outflow chimneys found in neutral hydrogen in galactic disks. At
the edge of the bubbles, the shocks traced by the OIII emission present a
curved magnetic field that parallels the bubble's shell. The magnetic field
follows the bubble expansion and binds the gas in the shell to trigger further
star formation. By analyzing the larger sample of 1694 bubbles, we found a
distinct radial-size distribution of bubbles in NGC\,628 indicating the star
formation history in the galaxy.
