We present the results of calculations of high-harmonic spectra at different mutual orientations of laser field and atomic angular momentum. The presented results show that the atomic current induced by the external laser field can include the longitudinal component orthogonal to the polarization vector of an incident field. Moreover, it provides an insight into the physics of processes which cause the polarization of generated harmonics. In addition, it hints at the way for the polarization control over high at harmonics.
