Earths New Magnetic Field 2025 Update. What is a Field Earth's Field DK Find Out The latest version of the World Magnetic Model (WMM), one of the key tools developed to model the change in Earth's magnetic field, has been released.The WMM is a spherical harmonic model of the Earth's main magnetic field and its slow temporal change The WMM is key to global navigation, ensuring that technological systems relying on the Earth's magnetic field operate correctly.

British explorer Sir James Clark Ross discovered the magnetic north pole in 1831 in northern Canada, approximately 1,000 miles (1,609 kilometers) south of the true North Pole. Now we have a more accurate map of magnetic north, one that should be good for another half a decade

National Oceanic and Atmospheric Administration, and in agreement with the British Geological Survey and the U.K Electricity can be generated from the energy of Earth rotating through. For the first time, a higher resolution map is also available, which offers more than 10 times more detail: it has a spatial resolution of about 300 km at the equator compared to the standard 3,300 km.
Earth's North Pole Is Moving Fast, And We Might Finally Know Why ScienceAlert. The WMM is also used for civilian applications, including navigation and heading systems. The release forecasts changes in Earth's magnetic field for the next 5 years as the magnetic north pole keeps moving faster leading to important improvements in global navigation systems.
What is the direction of lines of force of earth's field?. The World Magnetic Model (WMM) is the standard model for navigation, attitude, and heading referencing systems that use the geomagnetic field National Oceanic and Atmospheric Administration, and in agreement with the British Geological Survey and the U.K
