The Earth's magnetic pole is changing its location faster and faster!

in #steemstem2 years ago (edited)

The latest research shows that the north magnetic pole began to move unexpectedly from northern Canada towards Siberia with increasing speed.

Researchers gathered the latest magnetic field data from the last few years and included it in a model that made it possible to predict where the pole will be in the near future. This forecast will be used only for 2019. By the end of this year, a new magnetic field model will be released for 2020-2025. An unexpected change of the magnetic pole is of great importance for navigators around the world, including people responsible for military, sea and air navigation, as well as commercial airlines and other projects circling around the North Pole. Agencies such as NASA also rely on these models to measure and track satellites and air traffic management. Even companies that produce smartphones and navigations need a precise model to provide users with current maps, compass applications and GPS services.

Researchers have known since the nineteenth century that magnetic north isn't static. However, in the nineties, it began to move faster, from just 15 km per year to around 55 km per year. Interestingly, in the last few years magnetic north has approached the true north. The magnetic pole moved from a point in Canada to the north geographic pole. If he continues his way in the same direction, the geographic pole will pass and go further, this time on the other side of the Earth, that is, in Russia. The reasons for changing the pole position aren't completely known. What is disturbing is the increase in acceleration indicating significant changes occurring in the Earth's core.

Do you have any insight about the reasons of the speed increase? (I guess I should read the reference, but if you know I would be glad ;) )

Do you think this shift can cause a hemisphere flip?

Probably not. The magnetic pole usually circulates around the geographic pole. It would be disturbing for him to move significantly south.

Amazing planet we live on :-)

This is Interesting and that is why you may have to upgrade to newer phones that reset them selves periodically. Old phones (10 years ago) were always out by 10 to 100 meters on the GPS ordinates, after a year or so, I am curious of any research that the magnetosphere has the same, better or worse capabilities of protecting the earth form such thing as Sun flares, cosmic radiation, gama-rays and asteroid orbits are not affected by the migration of magnetic poles. The possibilities of our planets magnetics affecting the whole solar system should be studied closely, How about it NASA and my fellow astronomy enthusiasts should we continue with these theories. the possibilities are endless but it is good neurological exercising. Keep up the good work we may solve one of earths problem if not we will have fun trying.
