The North Magnetic Pole Has Changed And It Could Cause Major Issues

  • The Magnetic North Pole keeps moving about and it could be a problem

The north magnetic pole has been drifting so fast that it could be a problem for smartphone maps and navigation systems.

It may sound apocalyptic, but generally speaking, the shift is no cause for alarm. Research into rock signatures has shown that this can happen about every 250,000 years, except for the last one - that happened around 780,000 years ago.

In general Earth's magnetic field is getting weaker, leading scientists to say that it will eventually flip, where north and south pole changes polarity, like a bar magnet flipping over. But even if this was the case, it doesn't mean sudden volcanic outbursts or swarms of quake clusters. "The continuous shift is an issue for compasses in mobile phones and some consumer electronics".

Maintaining an accurate measurement of the north magnetic is especially crucial since the WMM is used by United States and British military agencies, the North Atlantic Treaty Organization, and smartphone technology, like Apple or Google Maps. Over the next century, the northern magnetic pole continued to move at an average speed of six miles per year.

The model, which is commissioned by the British and USA military agencies, is typically updated every five years, the most recent being in 2015.

Dr Lathrop, who who wasn't part of the team monitoring the magnetic north pole said: 'It has changes akin to weather. A National Geographic post explains, the magnetic north is what your compass locates, which is defined as the point at which magnetic field lines point vertically down. Since 1831, the magnetic north pole in northern Canada has been moving across the Arctic toward Russian Federation.

Whales are also attuned to magnetic fields.

Earth's magnetic North Pole has been wildly shifting towards Russian Federation so quickly that scientists have been forced to publish an update on its actual location a year early.

Dr Lathrop sees a flip coming sooner rather than later because of the weakened magnetic field and an area over the South Atlantic has already reversed beneath Earth's surface.

Scientists first recorded the position of the northern magnetic pole in 1831. Global Positioning System isn't affected because it's satellite-based. Smartphone users also rely on WMM data for accurate compass apps, maps, and Global Positioning System. This is the reason why they need to be recalibrated to reflect the change in the magnetic north pole.

Also, migratory animals such as birds, butterflies, and whales use the magnetic field for directions. "They were caused by processes in the core that we don't yet understand". "The magnetic field (changes) continuously, but it is partly because of its natural behavior". To compensate, the US' National Geospatial-Intelligence Agency and the United Kingdom's Defence Geographic Centre have combined to build the World Magnetic Model.
