magnetic pole shift

A magnetic pole shift occurs when Earth's magnetic north and south poles gradually move and eventually swap places. This process involves changes in the Earth's molten iron core, which generate the planet's magnetic field. Over thousands to millions of years, the magnetic poles can drift and flip, causing temporary magnetic disorientation. Such shifts have happened multiple times in Earth's history and do not directly harm the planet but can affect navigation systems and animals that rely on Earth's magnetic field. The process is natural and part of the Earth's geodynamic behavior.
