Persistent currents in mesoscopic systems made of a very clean metal and with nearly flat Fermi surface are studied. It is shown that the inclusion of the orbital magnetic interaction between electrons can lead to sponta­neous currents (spontaneous fluxes) and to quantized flux trapping if the number of interacting electrons is large enough: The energy of the system is discussed and the self-consistent formulas for the spontaneous flux and for the quantized flux in the system is derived. The influence of the spin on the presented phenomena is discussed.
