evidence: Unlike the geographic poles, Earth’s magnetic poles are not fixed and tend to wander over time. British polar explorer James Clark Ross first identified the Magnetic North Pole on the Boothis Peninsula in Canada’s Nunavut territory in 1831, according to the Antarctic travel site Antarctic Logistics. Since its discovery, the magnetic north pole moves about 25 miles (40 kilometers) a year in a northwest direction according to the Royal Museums Greenwich. What is more, Earth’s magnetic poles have also ‘flipped’ whereby north becomes south and south becomes north. These magnetic reversals occur at irregular intervals every 200000 years or so. [...] According to Science Daily, in the last 200 million years alone, Earth’s magnetic poles have reversed hundreds of times in a process where north becomes south and south becomes north. The magnetic poles flip approximately every 200,000 to 300,000 years according to NASA, though it has been more than twice that long since the last reversal. Earth’s most recent magnetic reversal occurred approximately 790,000 years ago so we are rather overdue for another. But don’t worry, the magnetic poles won’t just switch overnight, it can take hundreds or even thousands of years for the poles to flip.
