The secular variation of Earth's magnetic field

Nature volume 317, pages 777–781 (1985)Cite this article

Abstract

Models of the magnetic field at the core–mantle boundary at selected epochs from 1715.0 to 1980.0 reveal novel features in the field at the core. These suggest that the flow of core fluid is coupled to the mantle, and that magnetic diffusion is significant.
