a group of researchers at the Carnegie Institution for Science made this discovery in which it was revealed that hundreds of millions of years ago, the Earth’s magnetic field was completely different from the current, published ABC.
it is known that the magnetic field by the movement of the outer core is generated and at the same time, . to heat loss and the solidification of the inner core of the planet

the study results show that about one billion years ago, Earth may having gone through a transition from a strong magnetic field, with two opposites in the north poles and south of the planet, a weak magnetic field, which was caused not by two but by several different magnetic poles, the paper said.
Peter Driscoll, who led the research, said:
what I found was a surprising amount of variability. The new models do not support the idea of a stable field of two poles all the time, quite contrary to what we thought until now. “
For now, if Driscoll’s right it would to rewrite much of what is known about the geological past of the planet, says the Spanish average.
Indeed, the results have important implications for thermal and magnetic history of the Earth especially for rebuild continental and movements past climates, concludes ABC.
