Earth magnetic field flipped
WebJan 27, 2024 · It is speculation, but this might foreshadow a ‘magnetic reversal’ in which the magnetic north and south poles change locations. This has happened 171 times in the past 71 million years – and we are overdue a flip. Models of the Earth’s magnetic field based on satellite observations have shown that the present wandering is the result of ... WebMar 28, 2016 · If one “plays the tape backwards,” the record shows Earth’s magnetic field strengthening, weakening, and often changing polarity. Magnetic North and South Poles have even reversed or “flipped,” which is known as geomagnetic pole reversal. Geomagnetic pole reversals have happened throughout Earth's history.
