Description
A magnetic reversal can be defined as a change in the Earth's magnetic field between normal polarity and reversed polarity. In normal polarity the magnetic lines of force enter Earth at the north magnetic pole, which lies near the geographic north pole. The magnetic lines of force leave the Earth at the south magnetic pole, which lines near the geographic south pole. In reversed polarity the north magnetic pole lies near the geographic south pole, while the south magnetic pole lies near the geographic north pole.
