Earth’s Magnetic North Pole Is Shifting South… So What Now?

The Earth's magnetic poles are constantly shifting, and scientists believe they've figured out why. » Subscribe to Seeker!http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist The North and South poles are often thought of as the centers of magnetic North and magnetic South, but that isn’t necessarily the case. The magnetic North and South are really mobile and magnetic North, in particular, is moving faster than we originally thought it could. The prevailing theory about why our planet has a magnetic field, or magnetosphere, in the first place is called dynamo theory. Dynamo theory says the reason behind Earth’s magnetosphere is because of what lies underneath the crust. It’s the idea that the molten metals of Earth’s outer core, like iron, are being swirled all around the Earth’s interior, around the solid inner core, continuously creating electric currents as charged particles move through this liquid metal, and—in combination with the rotation of the Earth—becomes what’s called a dynamo: the source of a magnetic field. So because the liquid that creates the magnetosphere is always shifting, so are the magnetic poles. The science community is coming up with creative and experimental ways to to figure out the reasoning behind the magnetic poles shifting so quickly, and to further probe the Earth’s magnetic behavior. Earth’s magnetic field has flipped entirely in the past, we are long overdue for some magnetic migration, and it is happening at a rapid pace. So what does a shifting magnetic field actually mean for us?
