Earth's
magnetic North Pole has moved so quickly that authorities have had to formally
redefine the position of the magnetic North Pole. The extreme wandering of the
North Pole triggered increasing concerns over navigation, especially in high
latitudes.
Earth's
magnetic field is known to have moved and reversed in the geologic past.
Earth's magnetic field is a consequence of rotating molten iron and nickel
1,800 miles below the surface. As the continuous flow of molten metals in the
outer core varies over time, it changes the external magnetic field.
What we have
observed in the past hundred years is that the position of the magnetic North
Pole has drifted northward. That relocation of the magnetic North Pole was
transferred into overdrive in the past few years, triggering the pole to
quickly move. The increased speed with which the magnetic North Pole has
drifted driven authorities to formally update its position. The official site
of the magnetic poles is defined by the World Magnetic Model, which acts as the
foundation for navigation, communication, GPS, etc. everywhere on the globe.
The World
Magnetic Model updated their formal position of the magnetic north. The model
is usually updated every five years and was last restructured in 2015. Though,
the latest fast movement of the magnetic north derived researchers to update
the model early. In the recent past, the magnetic North Pole has shifted 34
miles a year in the direction of Russia. Just a half-century ago, the magnetic
North Pole was moving about 7 miles each year.
Earth's
magnetic North Pole is rapidly drifting from the Canadian Arctic toward Russia.
The model update guarantees the precision of work in governmental agencies
around the world. Specially, NASA, the Federal Aviation Administration (FAA)
and the U.S. Forest Service use the magnetic poles in their daily operations
from mapping to air traffic control. On a more personal level, smartphones use
the magnetic north for GPS location and compass apps.
