The core of our planet suddenly stops rotating in “The Core,” the Hollywood blockbuster, and the magnetic field of Earth collapses because of this event. After that, the Golden Gate Bridge is melted, and bursts of deadly microwaves cook the Colosseum. According to Justin Revenaugh, almost nothing in that movie is accurate, and he says that as a seismologist from the University of Minnesota. One thing is right: the planet is shielded by the magnetic field of the Earth from deadly and destructive solar radiation. Solar winds would otherwise strip Earth of its oceans and atmosphere.
But there is no staticity in the magnetic field of the planet. The Earth’s north magnetic pole (do not confuse is as it is not the same as geographic north) has offered scientists a lead to discovering a goose chase over the past century. This magnetic field moved to the north each year by an average of about 30 miles.
Earth’s North Magnetic Pole Is Not Moving As Estimated
The World Magnetic Model ( which tracks the field and informs navigation systems on planes and ships, compasses, and smartphone GPS ) has been made inaccurate by that movement. Since until 2020 no update is planned for the WMM, an unprecedented early update has been requested by the US military to account for the accelerated gambol of the magnetic north’s.
Now, insight has been gained by the authors of a new study into why there is still movement in the magnetic north, and they are trying to figure out a way to predict these shifts.
We can thank for the existence of the magnetic field of our planet to the swirling liquid iron and nickel that is in the outer core of the planet, located some 1,800 miles beneath the surface. In short, Earth’s northern magnetic pole is not moving as estimated.
