This paper reviews early attempts to deduce important constraints on the magnetic fields of high-redshift objects through a study of the rotation measure (RM) of QSOs. We have combined detailed studies of RM and optical spectra of 48 QSOs and have statistically analysed RM data on 116 objects and conclude that the objects which give rise to QSO metal-line absorption are also responsible for the observed extragalactic component of RM. This allows us to estimate their average magneto-ionic properties.
