We report a discovery of the circularly polarized CH $A^2\Delta-X^2\Pi$ and$B^2\Sigma^- -X^2\Pi$ molecular bands in the spectrum of the DQ white dwarf GJ841B. This is only the second such object since the discovery of G99-37 in the1970s. GJ 841B is also the first WD to unambiguously show polarization in theC_2 Swan bands. By modeling the intensity and circular polarization in the CHbands we determine the longitudinal magnetic field strength of 1.3 +- 0.5 MGand the temperature of 6100 +- 200 K in the absorbing region. We also presentnew observations of G99-37 and obtain estimates of the magnetic field strength7.3 +- 0.3 MG and temperature 6200 +- 200 K, in good agreement with previousresults.
