The Earth’s Magnetic North pole often moves from its original position. Now it is moving from the Canadian Arctic towards Siberia. According to the National Oceanic and Atmospheric Administration (NOAA’s), National Centers for Environmental Information (NCEI) the drifting speed of the Magnetic North pole has gathered pace in the past decades. The average speed of the Magnetic North Pole is 55 km/year. It will impact the navigation relation activities mainly in the high latitudes.

Magnetic field of the Earth

  • Earth has two north poles True North Pole or Geographic North Pole and Magnetic North Pole.
  • The True North Pole or Geographic North Pole remains fixed, the Magnetic North Pole shifts according to the Magnetic field of the Earth.
  • The presence of Molten Iron from the earth’s core and the constant rotation of the earth around its axis are the reasons behind changing the magnetic field of the earth.
  • The compass needle generally points out at the earth’s magnetic north pole.
  • The angle between the true North Pole and the magnetic north pole of a compass is known as the Angle of Declination.
  • Sometimes the Angle of Declination will become zero.
  • The true North Pole and magnetic north pole will unite and it would happen once in more than 3 centuries.
  • But this alignment lasts for only a few weeks it occurred in the October, 2019.
  • The Earth’s Magnetic North Pole was first discovered in 1831, since then it traveled around 2,250 Km.
  • The government agencies like NASA, the Federal Aviation Administration (FAA), US forest service utilize the earth’s magnetic north poles in their everyday operations for mapping to air traffic control.
  • Every five years the world Magnetic Model (WMM) needs to update to keep the model accurate.
  • WMM helps in to mapping the Planets and calculate the rate of change over passing time.
