There&#8217;s the geographic North Pole, which never changes. And there&#8217;s the magnetic North Pole, which is always on the move. And right now it&#8217;s moving faster than usual.<\/p>\n<p class=\"\">Over the past 150 years, the magnetic North Pole has casually wandered 685 miles across northern Canada. But right now it&#8217;s racing 25 miles a year to the northwest.<\/p>\n<p class=\"\">This could be a sign that we&#8217;re about to experience something humans have never seen before: a magnetic polar flip. And when this happens, it could affect much more than just your compass.<\/p>\n<p class=\"\"><strong class=\"\"><a href=\"https:\/\/alannamitchell.com\/\" target=\"_blank\" rel=\"noopener\">Alanna Mitchell<\/a>:<\/strong> Right now on the surface of the planet, it looks like it&#8217;s just a bar magnet. Our compasses are just pointing to one pole at a time because there&#8217;s a dominant two-pole system.<\/p>\n<p class=\"\">But sometimes, Earth doesn&#8217;t always just have a single magnetic North and South Pole. Evidence suggests that, for hundreds to thousands of years at a time, our planet has had four, six, and even eight poles at a time. This is what has happened when the magnetic poles flipped in the past. And when it happens again, it won&#8217;t be good news for humans.<\/p>\n<p class=\"\">Now you might think, eight poles must be better than two. But the reality is that: Multiple magnetic fields would fight each other. This could weaken Earth&#8217;s protective magnetic field by up to 90% during a polar flip.<\/p>\n<p>\u00a0\u2026click on the above link to read the rest of the article\u2026<\/p>\n<\/div>\n<\/div>\n<\/section>\n<\/section>\n<\/section>\n<\/article>\n<\/div>\n<\/section>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>What will happen when Earth&#8217;s north and south poles flip Earth&#8217;s magnetic field is what protects our planet from harmful space radiation.
