Earth’s north magnetic pole shifting
Earth’s magnetic field is what allows us to exist on Earth. The magnetic field of the Earth is surrounded in a region called the magnetosphere.
The magnetosphere prevents most of the particles from the sun, carried in solar wind, from hitting the Earth.
But now some strange thing happening to our Earths magnetic field
The Earth’s magnetic pole is moving at about 50 km (30 miles) a year.
Earth’s north magnetic pole has been skittering away from Canada and towards Siberia
Scientists thinking that this caused by liquid iron sloshing within the planet’s core.
The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move.nature reports
The moving pole affected navigation system, mainly in the Arctic Ocean north of Canada. NATO and the US and British militaries are among those using the magnetic model, as well as civilian navigation.
The wandering pole is driven by unpredictable changes in liquid iron deep inside the Earth.
The recent shifts in the north magnetic pole would be unnoticed by most people outside the Arctic, for instance using smartphones in New York, Beijing or London.
“It doesn’t really affect mid or low latitudes,” But “It wouldn’t really affect anyone driving a car.”
North magnetic pole forces need urgent navigation fix
Scientists must periodically update the World Magnetic Model to map this process, and the most recent version – produced in 2015 – was intended to last until 2020.
However, the magnetic field has been changing so quickly and erratically that while conducting a routine check in early 2018, British and US researchers realised drastic steps were needed.
The shift they observed was so large it was on the verge of exceeding the acceptable limit for navigation errors.
To account for this, scientists at the British Geological Survey and the US National Oceanic and Atmospheric Administration are issuing an unprecedented emergency update to the model.
An update will be released on January 30, the journal Nature said, delayed from January 15 because of the US government shutdown. The changes are essential as the system is used by aircraft, ships and even smartphones.
