The magnetic north pole is drifting about 34 miles a year. It crossed the international date and departs from the Canadian Arctic on the road to Siberia. So the question arises, who'll be affected?
Earth's north magnetic pole was drifting so quickly in the last few decades that previous estimated are no longer accurate enough for navigation. On Monday, an update of where true north was released almost a year ahead of schedule.
The magnetic north pole is drifting about 34 miles a year. It crossed the international date and departed from the Canadian Arctic on the road to Siberia.
So the question arises, who'll be affected? "The continuous shift is an issue for compasses in mobile phones and some consumer electronics. Aeroplanes and ships rely on magnetic north, generally As backup navigation,'' said University of Colorado geophysicist Arno Shullya, lead author of the recently released World Magnetic Model.
GPS navigation isn't affected because it is satellite based. The military depends upon where magnetic north is intended for navigation and parachute drops, whereas NASA, the Federal Aviation Administration and the US Forest Service use it.
Airport runway names are based on their direction toward magnetic north, and their names change when the sticks moved. Also, the US and UK tend to update the location of the magnetic north pole every five years in December, however, this update came due to the pole's faster movement.
Generally speaking, Earth's magnetic field is getting weaker, leading scientists to believe it'll ultimately reverse, where south and north pole changes like a bar magnet. It's happened many times in Earth's past, but maybe not in the last 780, 000 years. It is not a question of if it's going to reverse, the question is when it's going to reverse.
