Rather, it more closely points toward the [6]North Magnetic Pole of the Earth. The North Magnetic Pole is currently located in northern [7]Canada. It wanders in an [8]elliptical path each day, and moves, on the average, more than forty meters northward each day. [9]Evidence indicates that the [10]North Magnetic Pole has wandered over much of the Earth's surface in the 4.5 billion years since the Earth formed. The [11]Earth's magnetic field is created by [12]Earth's partially ionized outer core, which rotates more rapidly than the Earth's surface. Indicated in the above picture is [13]Ellef Ringnes Island, the current location of [14]Earth's North Magnetic Pole. _Tomorrow's picture: _[15]The Rings of Circinus _________________________________________________________________ [16]< | [17]Archive | [18]Index | [19]Search | [20]Calendar | [21]Glossary | [22]Education | [23]About APOD | [24]> _________________________________________________________________ _Authors & editors: _[25]Robert Nemiroff ([26]MTU) & [27]Jerry Bonnell ([28]USRA) _NASA Technical Rep.: _[29]Jay Norris.
