Abstract The effect on magnetic flux-tubes formation and equllibrium of the DC currents generated in the tubes by radial and azimuthal motions are investigated. These currents are found to be high enough to modify significantly the horizontal and vertical pressure distribution distribution at photospheric level. Consequently a radial variation of pressure can also be created and maintained at chromospheric levels leading to diffusion of neutral particles across the lines of force. The leakage of neutrals procedures a rise of the degree of ionization in the flux-tube and an enrichment in elements of high first ionization potential.
