Earth's magnetic poles are shifting unpredictably, with rapid drifts and weakening fields raising questions about a possible future reversal and its global effects.
Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.
On the other hand, NOAA says the Magnetic North Pole is a “geomagnetic field” our planet produces. Britannica says British naval officer Sir James Clark Ross discovered it in 1831.
