A model is developed in which the submillimeter excess recently measured in a rocket experiment is explained as emission from extragalactic dust heated by Population III stars. The linear polarization expected in such a background if a universal magnetic field (UMF) is present in the universe is calculated. This is compared with existing polarization upper limits in order to get information about the UMF. For a wide range of the important parameters, the present strength of the magnetic field should be lower than 5 x 10 to the -10th G. 26 refs.
