Linear polarization (left) and circular polarization (right) of ideal setup BE_toro with inclination angles of 3° (top), 45° (middle) and 87° (bottom), a constant dust temperature T_d = 15 K, a characteristic radius R_c = 1100 AU and a density n₀ = 10¹³ m^-3 in the center. We added an offset angle of 90° to the vectors of linear polarization to match the projected magnetic toroidal field. The dust particles are perfectly aligned.
