Abstract Prominences are thin structures consisting of cold plasma embedded in the hot corona. Because the plasma beta is low, the magnetic field plays a key role in all the processes involved. During their quiescent stage, magnetic measurements can be made inside them. These give local but also direct information on the neighbouring coronal field. Our understanding of the formation of prominences simultaneously improves our knowledge about the coronal magnetic field. Based on our present observational and theoretical understanding of prominences, this review will attempt to answer the following questions: What are the magnetic configurations favourable for the formation of prominences? What can we learn about the coronal magnetic field from the study of prominences? How can prominence plasma be formed?
