HALLEY1 first noticed that the magnetic declination at a number of sites changed with time in a manner that was consistent with a steady westward drift of the magnetic field relative to the surface of the Earth. After long neglect, interest in westward drift was revived by the work of Bullard et al.2, who examined the westward drift of the non-dipole part of the field, which they considered to originate less deep within the core than the slower moving dipole field. Since then, there have been… CONTINUE READING
