Shifting Location: The Magnetic North Pole has been drifting from the Canadian Arctic towards Russia, moving at a rate of around 10 kilometers per year. This shift has become more rapid in recent years.
Impact on Navigation Systems: The change affects compass readings and the accuracy of navigation systems that rely on Earth’s magnetic field, such as those used in aviation, marine navigation, and GPS technology.
Geomagnetic Reversal: While not a complete geomagnetic reversal (where the North and South magnetic poles switch places), the ongoing movement of the Magnetic North Pole is part of the Earth's dynamic magnetic field.
WGS-84 Update: The World Geodetic System (WGS-84), which is used for GPS mapping and navigation, needs to be updated to account for the shift in the Magnetic North Pole, ensuring more accurate positioning and directions.
Effect on Satellites: The change can also impact satellite-based navigation systems that rely on geomagnetic data. These systems need constant adjustments to accommodate the Earth's shifting magnetic field.
Scientific Research: The movement of the Magnetic North Pole is a subject of study, as scientists seek to understand the causes of the shift, such as interactions within the Earth's liquid outer core, which generates the magnetic field.
Not a Threat to Life: Despite the changes, the movement of the Magnetic North Pole does not pose a direct threat to life or health. It's a natural process that has occurred throughout Earth’s history.
