Geomagnetic polarity reversal

Term · Oil and gas · MLC-T-OAG-001673

A phenomenon where the Earth's magnetic field flips, causing the magnetic north and south poles to swap positions. This event is recorded in the magnetic signatures of rocks as they form, creating a striped pattern on the ocean floor. These reversals occur irregularly, with the last major one happening approximately 780,000 years ago.
