Over recent years, our understanding of protoplanetary disc (PPD) dynamics have changed dramatically. It is now believed that MHD processes are playing a very important role in the formation and evolution of these objects. While a direct measurement of magnetic fields in PPDs is still lacking, I will show in this seminar that several observed features can easily be explained as a natural consequence of magnetised discs. In this context, I will revisit the problems of grain transport and accumulation, disc clearing and planet migration.
