Over the past centuries, Earth&#8217;s magnetic north has been drifting east at an accelerating pace, shifting thousands of kilometers across the globe. The massive, compass-wobbling trend is being driven by vast oceans of liquid metal in Earth\u2019s interior and some fundamental principles of electromagnetism.<\/p>\n<p>Since the 1830s, the north magnetic pole of Earth <a href=\"https:\/\/www.iflscience.com\/environment\/earths-magnetic-north-pole-may-have-just-officially-shifted\/\" target=\"_blank\" rel=\"noopener\">has relocated<\/a> some 2,250 kilometers (1,400 miles) across the upper stretches of the Northern Hemisphere from Canada towards Siberia.\u00a0<\/p>\n<p>The magnetic north pole\u2019s travel seems to be accelerating too. Between 1990 and 2005, the rate of pole movement increased from less than 15\u2009kilometers (9.3 miles) per year to around 50 to 60\u2009kilometers (31 to 37 miles) per year, according to a <a href=\"https:\/\/www.nature.com\/articles\/s41561-020-0570-9\" target=\"_blank\" rel=\"noopener\">2020 study<\/a>.<\/p>\n<p>If it continues at this pace, the north magnetic pole will travel up to 660\u2009kilometers (410 miles) toward Siberia over the next decade. The effect is so profound that scientists at the British Geological Survey (BGS) <a href=\"https:\/\/www.iflscience.com\/earths-magnetic-north-pole-is-skittering-wildly-across-the-arctic-by-2040-our-compasses-will-point-eastward-of-true-north-says-expert-54541\" target=\"_blank\" rel=\"noopener\">have previously said<\/a> that all compasses will \u201cprobably point eastward of true north\u201d by 2040.<\/p>\n<p>On the other side of the planet, Earth\u2019s south magnetic pole also <a href=\"https:\/\/www.ncei.noaa.gov\/media\/3631\" target=\"_blank\" rel=\"noopener\">appears to be on the move<\/a>, drifting eastwards over Antarctica&#8217;s coast. These changes may seem extreme, but bigger shifts are possible. Every 300,000 years or so on average, Earth&#8217;s\u00a0<a href=\"https:\/\/www.iflscience.com\/what-happens-during-a-magnetic-pole-reversal-76422\" target=\"_blank\" rel=\"noopener\">magnetic poles swap entirely<\/a>; the north pole is transformed into the south pole and the south pole becomes the north pole. Since the last pole swap was 780,000 years ago, some think we&#8217;re long overdue for a switch-up.\u00a0<\/p>\n<p><span contenteditable=\"false\" draggable=\"true\" class=\"fr-video fr-deletable fr-fvc fr-dvb fr-draggable\"><iframe loading=\"lazy\" title=\"Magnetic Declination from 1590-2020\" width=\"1170\" height=\"878\" src=\"https:\/\/www.youtube.com\/embed\/wL2a1jnE61E?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><span class=\"fr-mk\" style=\"display: none;\">\u00a0<\/span><\/iframe><\/span><\/p>\n<p>Earth&#8217;s magnetic poles are the result of molten iron and nickel sloshing around its outer core. These liquid metals are conductive and in constant motion due to the planet&#8217;s rotation and heat-driven convection. In tune with the principles of electromagnetism, the movement creates electric currents, which generate a magnetic field.\u00a0<\/p>\n<p>This is known as Earth\u2019s geodynamo system or the dynamo theory. As we\u2019ve seen in recent shifts, the magnetic poles aren\u2019t constant and the geodynamo system can appear fairly chaotic.\u00a0<\/p>\n<p>As explained by the 2020 study mentioned above, the recent shift towards Siberia is possibly <a href=\"https:\/\/www.iflscience.com\/earths-north-magnetic-pole-is-heading-towards-siberia-and-scientists-now-know-why-55946\" target=\"_blank\" rel=\"noopener\">caused by a change<\/a> in the pattern of flow in Earth&#8217;s interior that occurred between 1970 and 1999. The change resulted in the Canadian &#8220;blob&#8221; becoming elongated and losing its influence on the magnetosphere, causing the pole to slip toward Siberia.<\/p>\n<p>At least, that\u2019s one current theory.<\/p>\n<p>\u201cWe know there are irregular changes in the planet\u2019s liquid outer core and that the magnetic field is also weakening under Canada, but it\u2019s not yet possible to say exactly for sure why magnetic north is changing so fast,\u201d Ciar\u00e1n Beggan, BGS Geophysicist, said in a <a href=\"https:\/\/www.bgs.ac.uk\/news\/will-santa-get-home-safe-new-world-magnetic-model-reveals-movements-in-the-earths-magnetic-field\/\" target=\"_blank\" rel=\"noopener\">2019 statement<\/a>.<\/p>\n<p>The shifting pole will have minimal impact on your day-to-day life (unless you\u2019re a pre-modern sailor <a href=\"https:\/\/www.iflscience.com\/can-you-think-yourself-well-find-out-more-in-issue-23-of-curious-out-now-74445\" target=\"_blank\" rel=\"noopener noreferrer\">navigating<\/a> unchartered seas). However, scientists must keep an eye on its movement as the Global Positioning System (GPS) and other satellite-based radio navigation systems will need to be recalibrated with the shift in mind.<\/p>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.iflscience.com\/why-is-earths-magnetic-north-pole-moving-eastwards-across-the-globe-76827\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Earth\u2019s magnetic poles aren\u2019t set in stone (or ice).
