= Geomagnetic excursion
{wiki=Geomagnetic_excursion}
A geomagnetic excursion is a temporary, significant change in the Earth's magnetic field, characterized by a rapid and substantial shift in the position of the magnetic poles. Unlike geomagnetic reversals, which involve a complete flip of the Earth's magnetic field (where the magnetic north and south poles switch places), excursions are generally shorter-lived events that can last from a few centuries to a few thousand years.
