Photospheric observations of the magnetic oscillations have been carried out to research magneto-acoustic waves in spots. The coupling between the magnetic field and the p-modes has been studied using reduced areas on the solar disk, but a global scenario is still missing. Four hour full-disk magnetograms ( at 4 arcsec/pix spatial resolution) obtained in the sodium D-lines were analysed pixel-by-pixel ( locally) and using the spherical harmonics decomposition ( globally). Magnetic oscillations were detected at different frequencies and identified on the solar disk. The global properties of the magnetic oscillations, shown via the l-nu diagrams, are for the first time presented and discussed.
