This poster describes the first results of a study of magnetic Ap stars in nearby northern open clusters. Using the MuSiCoS spectropolarimeter on the 2 m Bernard Lyot telescope at Pic du Midi observatory, high-resolution circular polarisation spectra have been obtained for 9 Ap stars proposed as members of 4 open clusters (M 39, IC 4756, the Pleiades and the Hyades). The aim of this study is to explore the evolution of chemical peculiarities and magnetic fields of Ap stars.
