The artificial magnetic fields engineered for ultracold gases allow the study of mixtures of two atomic species carrying different synthetic charges. We consider bosonic and fermionic mixtures in one-dimensional ring geometry and coupled to the magnetic field via the orbital effect. For unequally charged Bose mixtures, the resulting angular momentum transfer between the components yields stability regions in the phase diagram as a function of the inter-component interaction and the magnetic field. For unequally charged Fermi gases, the asymmetric orbital coupling to the magnetic field favors an optimum finite center-of-mass momentum pairing. The advantages of the unequally charged Fermi systems orbitally coupled to the magnetic field will be pointed out for the resulting Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) state.
