Earth’s Magnetic Field Drives North Magnetic Pole Close to Siberia

Planet Earth is shifting its movement and is driving the North Pole towards Siberia away from Canada.

Researches indicate that the planet evolved a magnetic field more than four billion years ago. The Earth’s magnetic field developed because of the melted iron that exists in the planet’s core and continues to churn about through convection currents. The continuous swirling and flowing of smelting iron generates a complicated sequence of magnetism and makes it hard to model and precisely forecast.

The planet’s magnetic poles have a tendency to insignificantly change over the course of time. It can advance a number of kilometers in a year. However, the frequency of its activity has been increasingly abnormal and still baffles scientists.

The North Pole’s bizarre activity is chiefly the outcome of the Earth’s liquid-iron outer core, called the core field. Other factors include magnetic minerals embedded in the in the crust and upper mantle. Electric currents generated by seawater flow also contribute, however, these conditions are small compared from the core field.

There was a powerful geomagnetic pulse that occurred in 2016 under South America. It could possibly further the existing sudden switch in the Earth’s magnetic field.

University of Leeds geomagnetist Phil Livermore unveiled in the latest American Geophysical Union meeting that there are two enormous patches of the magnetic field. One lies under Canada and the other patch could be found under Siberia. These patches possibly control the position of the north magnetic pole.

Livermore said, “The location of the north magnetic pole appears to be governed by two large-scale patches of magnetic field, one beneath Canada and one beneath Siberia. The Siberian patch is winning the competition.”

Due to this unexpected event, the present model of the Earth’s magnetic field becomes now outdated when in fact it was just updated three years ago. This makes the scientists prepare a new representation known as the World Magnetic Model. It should have been published today (Jan.15) but is delayed to Jan. 30 in lieu of US government shutdown.

Once the updated model became public, it will convey a wide range of navigation. This will encompass those shepherding airplanes and ships to people visiting Google Maps using their devices.

Another model is called the  International Geomagnetic Reference Field. It monitors the so-called declination or the distinctness between true or geographic North Pole and magnetic north where the compass needle usually points. Based on the 2015 model, the knowledge regarding the declination for points throughout the globe enables the precise conversion between a magnetic direction and a true point of reference. This orients aircraft, antennas, drilling machine and ships among others.

The most recent World Magnetic Model was developed to last until 2020. However, because of the immense, hasty and sudden rise toward Siberia, scientists need to revise the model early.

For the meantime, researchers are attempting to specifically identify why magnetic north is driving toward Siberia. One theory points to its accelerated navigation linked to the expeditious jet of liquid iron underneath Canada.
