00:00Earth has a magnetic field, including two magnetic poles, North and South.
00:08However, despite it being a seeming constant, experts say humans have been tracking those
00:12points for centuries, and they are actually moving.
00:15This is nothing new, with experts having tracked the magnetic north to the northern coast of
00:19Canada and more recently into the Atlantic Ocean in the 90s.
00:22However, now it's on the move again, heading towards Siberia in Russia.
00:26Historically, the magnetic north pole has moved at a rate of around 6 miles per year.
00:30However, since the turn of the century, it's sped up.
00:34Experts say at that point, it started moving at a rate of around 34 miles per year, slowing
00:38down to 22 miles a year more recently.
00:41So is this going to literally throw off every compass on the planet?
00:43Well, yes and no.
00:45The position of true north versus the magnetic north pole will certainly be at odds.
00:49However, those using traditional compasses should be aware of magnetic declination and
00:53adjust accordingly.
00:54For the rest of us, digital pathfinding using GPS is adjusted by the British Geological
00:59Survey and the US National Oceanic and Atmospheric Administration.
01:03So no need to worry.
01:04The magnetic north pole moves because the Earth's innards are liquid, meaning its
01:08outer core has a constantly moving layer of conductive material, which generates an electric
01:13current.
