Magnetic North Pole's 'Pretty Fast' Moving to Russia's Siberia - Scientists

North is not quite where it used to be.

The update released on Monday says the magnetic north pole is moving about 34 miles (55 kilometres) a year.

The magnetic south pole is moving far slower than the north.

The pole is moving about 34 miles a year, scientists say, crossing the worldwide date line in 2017 on a journey towards Russian Federation.

"This out-of-cycle update before next year's official release of WMM2020 will ensure safe navigation for military applications, commercial airlines, search and rescue operations, and others operating around the North Pole".

Nature recently reported: "The fast motion of the north magnetic pole could be linked to a high-speed jet of liquid iron beneath Canada".

Since 1831 when it was first measured in the Canadian Arctic it has moved about 1,400 miles toward Siberia.


It might sound like something out of a Hollywood disaster movie, but the world's magnetic northern pole has changed.

Federal organizations like NASA and the Federal Aviation Administration use something called the World Magnetic Model for navigational purposes as well as surveying and mapping, satellite tracking, and air traffic management.

"The declination has changed just over 2.5 degrees over the past 22 years since Denver opened", Heath Montgomery, former Denver International Airport spokesperson, said in a statement after the last update.

In general Earth's magnetic field is getting weaker, leading scientists to say it will eventually flip, where the North and South poles change polarity, like a bar magnet flipping over.

It could be thousands of years before the magnetic field reverses again, the researchers believe.

'It's not a question of if it's going to reverse, the question is when it's going to reverse, ' Mr Lathrop said. "It didn't move much between 1900 and 1980 but it's really accelerated in the past 40 years", said Ciaran Beggan, of the British Geological Survey in Edinburgh.

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. Declination is important to compasses as it helps correct navigation systems for a variety of uses. The magnetic field shields Earth from some unsafe radiation, Lathrop said.
