Scientists Updated the World Magnetic Model Due to Fast-Moving Magnetic North Pole

The magnetic north pole of Earth is continuously changing its position, but it’s having a severe impact on navigation technology. Magnetic north pole never stands steady, or say it is restless. The magnetic north pole is the point that a compass recognizes as north, and it is different from the geographic North Pole. Currently, the magnetic north pole is present four degrees south of the geographic North Pole. Earth’s geographic North Pole is fixed, and the magnetic north pole roams in the direction of Siberia. The pole drifts at a speed of more than 34 miles per year. That speed of movement may seem slow, but the move forced researchers to update Earth’s magnetic field model.

The transformation took place a year earlier than scientists thought. So the new model will allow navigational services like map apps, to work precisely. Thus, researchers at National Centers for Environmental Information have offered an update to the “World Magnetic Model”. Scientists revealed that sudden changes in the Arctic region made the current magnetic north incorrect and faulty. The magnetic north pole is moving up from 9 miles every year from 2000. Although, humanity or any other thing cannot manage it. The float is a result of procedures taking place at the core of our planet. The compounds acting as metallic conductors for Earth’s magnetic field are responsible for the change. Nickel and molten iron overflow and roll in the core. As a result, the fluid flow introduces changes in the magnetic field.

Scientists keep track of the transforming magnetic field and change the World Magnetic Model after every five years. The next update was going to take place in the upcoming year, but some unplanned changes made it obligatory to change it in the current year. Arnaud Chulliat, a geophysicist at the University of Colorado Boulder and NOAA’s National Centers for Environmental Information (NCEI), said they regularly estimate the accuracy and quality of the model. They also compare it with newly available information. But the researchers noticed that the error the error increased relatively fast, particularly in the Arctic region. The new updated model is only for the current year. Chulliat said they would unroll a new World Magnetic Model to be used from 2020 to 2025.
