How Long Will Earth S Magnetic Field Last at Kendall North blog

How Long Will Earth S Magnetic Field Last. Over the last 2.6 million years alone, the magnetic field switched ten times — and, because the most recent occurred a whopping 780,000 years ago, some scientists believe we are overdue. Scientists map and track the overall shape and orientation of the earth's magnetic field using local measurements of the field's. Models of the earth’s magnetic field based on satellite observations have shown that the present wandering is the result of. A new study suggests the last field reversal 773,000 years ago took 22,000 years to occur, which could explain some of the inner workings of our planet’s core. That 2015 update was supposed to remain valid until 2020, arnaud chulliat, a geomagnetist at the university of colorado boulder and the national oceanic and atmospheric administration's. But a new study august 7 in science advances says we should probably calm down, since the last magnetic field reversal on earth took quite a bit longer: The earth’s magnetic field has flipped every 200,000 to 300,000 years for the past 20 million years, although it has been longer than that since the last flip. New research suggests a polarity reversal of the planet takes about 22,000 years, significantly longer than former estimates.
