Magnetic filed plays a crucial role in the evolution of the ISM and star formation process. However, how the magnetic field affects the accretion from core scale to envelope scale remains unclear, and studies on this topic are still limited. Investigating this relationship is essential for understanding how material collapse and accrete onto protoplanetary disk. In this study, we analyze the JCMT 850 µm and ALMA 850 µm polarized emission toward the Orion star-forming region to explore the magnetic field structure across different spatial scales. By comparing the observation results with our polarization models generated using POLARIS, we aim to uncover the physical mechanisms driving magnetic field variations from core to envelope scales and how these variations influence accretion.
