The aim of this project is to study the interstellar magnetic field in regions of the Small Magellanic Cloud (SMC) affected by the interaction between the Small and the LargeMagellanic Clouds. We use optical polarimetric data to detect the polarization fromaligned grains in the interstellar magnetic field of the SMC. The optical linear polarization will map the sky-projected direction of the magnetic field and allow us to determine characteristics of the SMC and Pan-Magellanic field structures. We will cross-correlate our results with those of point sources and structures found by the Sptizer satellite in the SMC between 3.6 and 8 microns. We will use the angles dispersion of the polarization vectors in this region to estimate the sky-projected component of the magnetic field intensity.
