Using the mechanism of radial ejection of cold mass from the solar surface, a numerical simulation is made of the formation, evolution and maintenance of prominences. The results show that, with the initial magnetic field taken to be that of a coronal streamer under magnetostatic equilibrium, the pile-up of the cooler and denser plasma will deform the closed magnetic field below the neutral sheet, making it flat and even concave in shape. The deformed field in turn supports the prominence material against gravity. This structure is maintained after the mass ejection ceases. It is thus demonstrated that magnetic field plays an important role in the formation and stable maintenance of prominences.
