科学家对南极地磁观察的資料整理后表明:在最近五十余年间,南磁极移动了約八百公里左右。目前,南磁极以每小时二米的速度移动,其运动的大致趋向,是从維多里亚地的阿尔倍托山向阿德里海岸移动。有趣的是,与此同时南非地磁异常不断增长,在三十年內南非的地磁場水平分量减少了15％(在南磁极,磁力綫是 The scientists’ data on the Antarctic geomagnetic observation show that in the past 50 years, the South magnetic pole has moved about 800 kilometers. At present, the South magnetic pole is moving at a speed of two meters per hour. The general trend of its movement is from the Albuto Mountain in the Victorian area to the Adriatic coast. Interestingly, at the same time, the geomagnetic anomaly in South Africa continues to increase. In the three decades, the horizontal component of geomagnetic field in South Africa has decreased by 15% (in the South magnetic pole, the magnetic field line is
