The most recent data on Earth's magnetic North Pole, which has formally relocated, is being sent into navigation systems on ships, aircraft, and submarines worldwide.
 
With regard to the location of the magnetic north pole, the most recent World Magnetic Model (WMM) 2025 offers more accurate navigational data for all military and commercial aircraft, ships, submarines, and GPS systems.
 
For navigational purposes, the united states and united kingdom governments, including the US Federal Aviation Administration and the US Department of Defense, as well as organizations like the North Atlantic Treaty Organization (NATO), use the WMM, which was co-developed by the british Geological survey (BGS) and NOAA National Centers for Environmental Information (NCEI).
 
WHAT IS MAGNATIC NORTH POLE AND WHY DOES IT MOVE?
The location on Earth's surface where the magnetic field points vertically downward is known as the magnetic north pole. Because of variations in the Earth's core, the magnetic North Pole is not static like the geographic North Pole, which is fixed.
 
The global positioning systems' (GPS) ability to work depends on the location of the magnetic north pole.
 
Earth's liquid outer core, which is mostly composed of molten iron and nickel, is what moves the magnetic north pole. Through a phenomena known as the geodynamo, these activities produce the Earth's magnetic field.
 
WHERE IS MAGNETIC NORTH POLE NOW?
The North Magnetic Pole was initially found in northern canada in 1831 by Sir james Clark Ross. The pole has been drifting toward russia over the Canadian Arctic since 1831.
 
In recent years, the magnetic north pole has been migrating more quickly. With its current location close to the Arctic Ocean, it traveled at a rate of around 10 km per year in the early 20th century and 55 km per year by 2000.
 
"Magnetic north has been moving slowly around canada since the 1500s but, in the past 20 years, it accelerated towards Siberia, increasing in speed every year until about five years ago, when it suddenly decelerated from 50 to 35 kilometres per year, which is the biggest deceleration in speed we've ever seen," William Brown of the BGS said.
 
High-resolution maps of the area have also been made public for the first time by researchers.
