The relative orientation between local magnetic field and Galactic plane
  in low latitude dark clouds
  In this work, we study the magnetic field morphology of selected star-forming
clouds spread over the galactic latitude ($b$) range, $-10^\circ$ to
$10^\circ$. The polarimetric observation of clouds CB24, CB27 and CB188 are
conducted to study the magnetic field geometry of those clouds from ARIES,
Manora Peak, Nainital, India. These observations are combined with those of 14
further low latitude clouds available in the literature. Analyzing the
polarimetric data of 17 clouds, we find that the alignment between the envelope
magnetic field ($\theta_{B}^{env}$) and Galactic plane ($\theta_{GP}$) of the
low-latitude clouds varies with their galactic longitudes ($l$). We observe a
strong correlation between the longitude (\textit{l}) and the offset
($\theta_{off}=|\theta_B^{env}-\theta_{GP}|$) which shows that
$\theta_{B}^{env}$ is parallel to the Galactic plane (GP) when the clouds are
situated in the region, $115^\circ<l<250^\circ$. However, $\theta_{B}^{env}$
has its own local deflection irrespective of the orientation of $\theta_{GP}$
when the clouds are at $l<100^\circ$ and $l>250^\circ$. To check the
consistency of our results, the stellar polarization data available at Heiles
(2000) catalogue are overlaid on DSS image of the clouds having mean
polarization vector of field stars. The results are almost consistent with the
Heiles data. The effect of turbulence of the cloud is also studied which may
play an important role in causing the misalignment phenomenon observed between
$\theta_{B}^{env}$ and $\theta_{GP}$. We have used \textit{Herschel}
\textit{SPIRE} 500 $\mu m$ and \textit{SCUBA} 850 $\mu m$ dust continuum
emission maps in our work to understand the density structure of the clouds.
