This work focuses on the study of the intra-cluster magnetic field in the poor galaxy cluster Abell 194. New total intensity and polarization observations of Abell 194 obtained with the Sardinia Radio Telescope were combined with archival Very Large Array observations to derive the spectral aging and the rotation measure images of the radio galaxies 3C40A and 3C40B embedded in the cluster. These data in combination with X-ray images are used to constrain the intra-cluster magnetic field properties. To date, the central magnetic field derived for Abell 194 is the weakest ever found using rotation measure data in galaxy cluster.
