<P> (The positions were less than 30 km (20 mi) apart .) </P> <P> The Canadian government has made several measurements since, which show that the North Magnetic Pole is moving continually northwestward . In 2001, an expedition located the pole at 81 ° 18 ′ N 110 ° 48 ′ W ﻿ / ﻿ 81.3 ° N 110.8 ° W ﻿ / 81.3; - 110.8 ﻿ (Magnetic North Pole 2001 location). In 2007, the latest survey found the pole at 83 ° 57 ′ N 120 ° 43 ′ W ﻿ / ﻿ 83.95 ° N 120.72 ° W ﻿ / 83.95; - 120.72 ﻿ (Magnetic North Pole 2007 location). During the 20th century it moved 1100 km, and since 1970 its rate of motion has accelerated from 9 km / year to approximately 52 km / year (2001--2007 average; see also Polar drift). Members of the 2007 expedition to locate the magnetic north pole wrote that such expeditions have become logistically difficult, as the pole moves farther away from inhabited locations . They expect that in the future, the magnetic pole position will be obtained from satellite data instead of ground surveys . </P> <P> This general movement is in addition to a daily or diurnal variation in which the North Magnetic Pole describes a rough ellipse, with a maximum deviation of 80 km from its mean position . This effect is due to disturbances of the geomagnetic field by charged particles from the Sun . </P> <Table> <Tr> <Td> North Magnetic Pole </Td> <Td> (2001) 81 ° 18 ′ N 110 ° 48 ′ W ﻿ / ﻿ 81.3 ° N 110.8 ° W ﻿ / 81.3; - 110.8 </Td> <Td> (2004 est) 82 ° 18 ′ N 113 ° 24 ′ W ﻿ / ﻿ 82.3 ° N 113.4 ° W ﻿ / 82.3; - 113.4 </Td> <Td> (2007) 83 ° 57 ′ N 120 ° 43 ′ W ﻿ / ﻿ 83.95 ° N 120.72 ° W ﻿ / 83.95; - 120.72 </Td> </Tr> <Tr> <Td> South Magnetic Pole </Td> <Td> (1998) 64 ° 36 ′ S 138 ° 30 ′ E ﻿ / ﻿ 64.6 ° S 138.5 ° E ﻿ / - 64.6; 138.5 </Td> <Td> (2004 est) 63 ° 30 ′ S 138 ° 00 ′ E ﻿ / ﻿ 63.5 ° S 138.0 ° E ﻿ / - 63.5; 138.0 </Td> <Td> (2007) 64 ° 29 ′ 49" S 137 ° 41 ′ 02" E ﻿ / ﻿ 64.497 ° S 137.684 ° E ﻿ / - 64.497; 137.684 </Td> </Tr> </Table>
