Observations with the 6 m telescope have revealed 25 new magnetic chemically peculiar stars. We selected candidates by analyzing the depression profile at a wavelength of 5200 Å. This technique for selecting candidate magnetic stars is shown to be effcient: we have found magnetic fields in 25 from 40 objects that were selected for observations with the Zeeman analyzer. 11 of the rest 15 objects have wide lines and therefore the accuracy of measuremets is low in these cases, so it is not unlikely that part of these stars are magnetic too. We found several stars with very strong magnetic fields, among them HD 178892 and HD 343872 with the surface magnetic fields not less than 20 kG and 9 kG, resp ectively. In spite of the good effciency of our method for selecting candidates, we have not found any correlation between the intensity of the depression profile and the value of the magnetic field.
