WHAT CAUSES THE SHIFTING OF EARTH’S MAGNETIC POLES?
The movement of Earth’s molten core generates the magnetic field. Changes in the internal forces within the core cause gradual shifts in the poles’ location and intensity.
HOW FAST IS THE NORTH MAGNETIC POLE MOVING?
Since the 1990s, the North Magnetic Pole has been moving from Canada towards Siberia at a rate of about 55 kilometers per year. Recent estimates indicate the rate has slowed to approximately 45 kilometers per year.
HAVE THE MAGNETIC POLES EVER REVERSED?
Yes, the most recent reversal occurred 780,000 years ago. These reversals are unpredictable and caused by fluctuations in the magnetic field due to the movement of metallic material in the outer core.
DO POLE REVERSALS CAUSE MAJOR DISASTERS?
Historical records show that previous pole reversals did not cause major extinctions or catastrophic events. However, they can lead to more vivid northern lights and temporary disruptions in communication systems.
HOW DOES THE SHIFTING OF MAGNETIC POLES AFFECT EVERYDAY LIFE?
• Compass Navigation: Regular updates to navigation systems are needed to account for shifting magnetic poles. • Northern Lights: The auroras become more vivid and visible at lower latitudes during pole shifts. • Communication Systems: Modern technology, such as GPS signals and satellite communications, could be temporarily affected.
WHERE WILL THE NORTH MAGNETIC POLE BE IN THE FUTURE?
In early 2019, NOAA estimated that the North Magnetic Pole would be located at 86 degrees North, 142 degrees East in 2024, and 138 degrees East in 2025.
