Abstract

There are remarkably few data on the intensity of the geomagnetic field in early China. New results reported here indicate that the total intensity of the magnetic field of the Earth in the region near Loyang (lat. 34°42′ N, long.112°40′ E) has changed considerably during the past 2,400 yr (500 BCAD 1900). The maximum value reached about 1,700 yr ago is as much as 54% higher than the present one.
