Popis: | 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 Comment: 22 pages, 7 figures.
