HAWC+ imaging polarimetry of OMC-1 in Orion. The Orion Bar is the linear feature to the SE and BN-KL is the bright region just NW of the center. Note that the position angle of the magnetic field as seen at 53 microns is perpendicular to the field as seen at longer wavelengths. The NIR polarimetry of BN, which samples ALL of the dust in FRONT of BN independent of dust temperature, agrees with the longer wavelength emission. The 53 micron emission preferentially samples the hotter dust surrounding BN, and that dust must have a magnetic field perpendicular to the cooler dust and the dust in front and at longer wavelengths.
