Time sequences of vector magnetograms and Hβ filtergrams of NOAA 7469 were obtained from April 4 to April 12, 1993 at Huairou Solar Observing Station of Beijing Astronomical Obervatory. The region was characterized by emergence of several new bipoles and formation of active magnetic interfaces between newly emerged and pre-existing magnetic flux. Based on the 3-D magnetic lines of force, calculated with boundary element method (BEM), it has been found that the topology of magnetic lines of force changes obviously when longitudinal magnetic fields evolve during the period of observations. Two active magnetic interfaces were identified from April 6 to 8 in this region. By comparing Hβ filtergrams with vector magnetograms of the photosphere and the 3-D magnetic lines of force, it is found that many flares initiated at the active magnetic interfaces.
