The study of polarized light is a powerful tool for the determination of magnetic fields in stellar objects. The most used methods are the so-called ``photographic'' method [1] and Balmer line photopolarimetry [2]. However, in various cases these two methods give different results for the same star. To assess the validity of the interpretation of photopolarimetric measurements of Balmer lines, we have developed a new model of the formation of these lines in a magnetized plasma. This model is based on the Simplified Unified Theory (SUT) for the computation of the line shape [3-5]. We present this model, some numerical results computed with it, and conclusions drawn from consideration of there results [6]. We discuss the prospects for future developments in continuation of this work. .
