Fig. 3

Motion of the magnetic dip pole (red) and geomagnetic pole (blue) since 1900 from IGRF-13 in the northern hemisphere (left) and southern hemisphere (right). The scale provides an indication of distance on the WGS84 ellipsoid that is correct along lines of constant longitude and also along the middle lines of latitude shown. Note the left and right panels use different longitude ranges. The maps use stereographic projection. International and provincial boundaries are drawn in the left panel
