For decades, magnetic north was steadily inching away from the geographic North Pole, but for the last few years the north magnetic pole has been moving closer to the North Pole.
The speed at which magnetic North moves has increased from 9 miles per year to 34 miles per year, leaving researchers in a tussle to track the changes.
The North Magnetic Pole is wandering about 34 miles a year. Currently, the northern magnetic pole is moving from the Canadian Arctic towards Siberia.
Airplanes and boats also rely on magnetic north, usually as backup navigation, said University of Colorado geophysicist Dr Arnaud Chulliat, lead author of the WMM.
Since the pole was first measured in 1831, it has moved an estimated 1,400 miles (2,300km) towards Siberia.
"Due to unplanned variations in the Arctic region, scientists have released a new model to more accurately represent the change of the magnetic field between 2015 and now", the US National Oceanic and Atmospheric Administration's National Center for Environmental Information wrote in a press release. Earth's magnetic field is created in its liquid outer core, which is made of liquid iron and nickel.
For most civilian purposes in Western Europe and North America, British Geological Survey geophysicist Ciaran Beggan says the changes would be relatively minor.
Maintaining an accurate measurement of the north magnetic is especially crucial since the WMM is used by U.S. and British military agencies, the North Atlantic Treaty Organization, and smartphone technology, like Apple or Google Maps. "This out-of-cycle update before next year's official release of WMM2020 will ensure safe navigation for military applications, commercial airlines, search and rescue operations, and others operating around the North Pole".
Turbulence in in the planet's core, where the motion generates an electric field, has caused the field to change in systems described as "akin to weather".
Even though the magnetic North Pole has never stayed idle, scientists have been left wondering as to why it has been moving so erratically.
NASA said: "The last time that Earth's poles flipped in a major reversal was about 780,000 years ago, in what scientists call the Brunhes-Matuyama reversal".
"It's not a question of if it's going to reverse, the question is when it's going to reverse", Lathrop said.
The entire transportation sector, especially aviation and shipping, depends on correctly knowing the position of magnetic north to chart out their navigation paths.
The magnetic field shields Earth from some unsafe radiation, Mr Lathrop said.
Earth's magnetic field is now getting weaker, and scientists believe the poles could "flip" at some point in the future.
As the system is used in modern technology, our mapping systems could be affected. The sudden and dramatic changes weren't anticipated by WMM's previous update.
'Your smartphone camera and various apps can use the magnetic field to help determine the direction you are facing, ' he continued.
