Why does Earth’s magnetic field move?
On any given day, it moves erratically by many tens of meters because of changes in the currents inside earth’s core, as well as the influence of electrical currents in the ionosphere, and the changing space environment due to solar storms and winds.
Do Earth’s magnetic poles move around?
Though the Earth’s magnetic field is very similar to that of a bar magnet, with a north and south pole, it is not as stable because it is generated by complex processes inside the Earth. These cause the magnetic poles to wander. Historically, the North Pole has moved at about 15 kilometres per year.
How often does the Earth’s magnetic field shift?
They can happen as often as every 10 thousand years or so and as infrequently as every 50 million years or more. The last reversal was about 780,000 years ago.
