Geomagnetic Intensity: Changes during the Past 3000 Years in the Western Hemisphere

Geomagnetic Intensity: Changes during the Past 3000 Years in the Western Hemisphere

V Bucha et al. Science. .

Abstract

A series of archeomagnetic measurements have been carried out on archeologic materials from Arizona and Mexico which can be compared with results from Europe and Asia. This comparison shows a westward drift of geomagnetic intensity at a rate of about 0.24 degree per year. Furthermore, an apparent coincidence between changes in the earth's magnetic moment and changes in the production rate of radiocarbon is observed.
