Magnetic Field Reversal

Magnetic field reversal is a natural process where Earth's magnetic North and South poles switch places. This occurs because the Earth's magnetic field is generated by the movement of molten iron in its outer core, creating a dynamic and changing magnetic environment. Over long periods, the flow patterns in the core can change, causing the magnetic poles to gradually move and eventually flip. These reversals happen irregularly, typically over thousands to millions of years, and do not pose direct danger to life, but they can affect animals that rely on Earth's magnetic cues and impact navigation systems.
