Scientists Warn Earth's Magnetic North Pole is Drifting at Fast Pace

The north magnetic pole has been drifting so quick that it has become an issue for Smartphone maps and navigation systems, scientists have warned.

"Due to unplanned variations in the Arctic region, scientists have released a new model to more accurately represent the change of the magnetic field between 2015 and now," the US National Oceanic and Atmospheric Administration's National Centers for Environmental Information said in a press release on Monday.

"Out-of-cycle update ... will ensure safe navigation for military applications, commercial airlines, search and rescue operations, and others operating around the North Pole,” it added.

Scientists first noticed the change in 2018 due to a "huge amount of satellite data," which showed the pole had gone beyond the model's predicted area, Ciaran Beggan, a geophysicist at the British Geological Survey, told CNN.

“The drift is caused by processes deep inside the planet,” he added.

“Earth's magnetic field is created in its liquid outer core, which is made of liquid iron and nickel. "As it flows it creates an electronic current and that current makes a magnetic field -- which drifts with the hot runny core.”

There is nothing to worry about, Beggan said. "It is unusual behavior in historical terms, (by) geological scales it is not unusual," he said.

"The magnetic field (changes) continuously, but it is partly because of its natural behavior.”
