We present the state-of-the-art results of an ongoing survey of the chemically peculiar star population in the association Ori OB1. Aiming to achieve uniform measurement of the magnetic field and other stellar parameters of the sample, from early 2011 we have collected over 500 spectra for more than 60 stars which had been classified in the literature as the bearers of peculiar spectra. With new measurements, we extended our knowledge about the magnetic field and multiplicity of the stellar population in Ori OB1.
