WASHINGTON -- North isn't quite where it used to be.
The magnetic north pole has been moving so fast that scientists on Monday released an update of where it really was, nearly a year ahead of schedule.
Earth's north magnetic pole is wandering about 34 miles (55 kilometres) a year. It crossed the international date line at the end of 2017. It's leaving the Canadian Arctic on its way to Siberia.
The shifting magnetic pole is a problem for compasses. Airplanes and boats also rely on magnetic north usually as backup navigation.
