Through the analysis of density of states (DOS), we study two different kinds of cyclic molecules, a sodium atomic circle and a Polycyclic Aromatic Hydrocarbons (PAH) molecule respectively under an external magnetic field. The results of calculation show that original DOS peaks split into two and the positions of peaks can be modulated periodically by controlling the magnetic field. We attribute this phenomenon to the interaction between the molecular orbital magnetic momentum and the magnetic field. Generally, this effect is obscure for a usual structure but obvious for the cyclic molecules.
