Earth’s magnetic poles flipping should not be a cause of concern for the humanity. The flipping of earth’s magnetic poles can cause enormous blackouts. Daniel Baker, the director of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, is proposing a turnaround would cause parts of planets unlivable.
Oceans of molten iron are spiraling into deep interior of the planet around the outer core. The splashing puts forth a massive bar magnet through Earth. The massive magnet poses at an angle of about 11 degrees from the axis, around which Earth spins, but these poles are wide apart unlike the geographic North and South poles.
Globules of iron get flung in the contradictory direction from iron atoms around them. Researchers elucidate that they become reverse-aligned. When the reversal of the iron atoms reaches its potential then the colossal bar magnet flips and magnetic north becomes magnetic south.
The flipping takes around 1000 to 10000 years. Monika Korte, the scientific director of the Niemegk Geomagnetic Observatory at GFZ Potsdam in Germany said that the flip is not unexpected, but a gradual process where the field strength becomes weak. Potentially the field renders more intricate and might show more than two poles for a while and then expands in strength in the opposite direction.
Magnetic north and south poles have exchanged places numerous times in Earth’s history about every hundred thousand years or so, scientists have found. The last one occurred about 780,000 years ago.
