This could happen by a few degrees or by many degrees.

WebAug 3, 2024 · During a pole reversal, Earth’s magnetic north and south poles swap locations. While that may sound like a big deal, pole reversals are actually common in Earth’s geologic history. Paleomagnetic records, including those revealing variations in magnetic field strength, tell us Earth’s magnetic poles have reversed 183 times in the last 83 ... WebSep 19, 2024 · Earth is not a perfect sphere. When it rotates on its spin axis -- an imaginary line that passes through the North and South Poles -- it drifts and wobbles. These spin-axis movements are scientifically referred to as "polar motion." Measurements for the 20 th century show that the spin axis drifted about 4 inches (10 centimeters) per year. Over ... WebMay 19, 2024 · The Earth’s spin axis is the figurative line about which the Earth rotates. The poles, north and south, are situated at either end of the spin axis. By contrast, the magnetic poles — the ones you can find using a compass — are usually offset from the geographic poles, and their location shifts with the magnetic field. infor pcf
