North Magnetic Pole Is Shifting Rapidly Toward Russia

New research shows the pole moving at rapid clip—25 miles (40 kilometers) a year.


Over the past century the pole has moved 685 miles (1,100 kilometers) from Arctic Canada toward Siberia


The shift is likely a normal oscillation of the Earth’s magnetic field, Stoner said, and not the beginning of a flip-flop of the north and south magnetic poles, a phenomenon that last occurred 780,000 years ago.


Such reversals have taken place 400 times in the last 330 million years, according to magnetic clues sealed in rocks around the world. Each reversal takes a thousand years or more to complete.


“People like to think something special is happening in their lifetimes, but despite the dramatic changes, I don’t see any evidence of it,” Stoner said. “It’s probably just a normal wandering of the pole.”
