Different magnetic features between solar polar and equatorial magnetic fields

Solar polar and equatorial photospheric (FeI lambda 5324.19 Angstrom line) magnetic fields have been observed using the vector video magnetograph at Huairou Solar Observing Station of Beijing Astronomical Observatory. It is found from our observations that the magnetic fields of small-scale magnetic features near the solar poles are stronger than in quiet equatorial regions near the limb, and that strong polar magnetic elements appear to have the same magnetic polarity as the general large-scale polar magnetic field, which is in agreement with previous results by Homann et al. (1997) and Zhang et al. (1997). It is also found from our observations that there are more opposite polarity magnetic pairs near the solar poles than in quiet equatorial regions near the limb.
