(Digital Journal) Could the world turn upside down — magnetically speaking that is? The answer is yes according to a new joint study by researchers from Europe and America — and a flip of Earth’s magnetic field could occur within our lifetimes.
Such a change would send every magnetic compass on Earth awry, with needles pointing south instead of north.
Historically, it would by no means be the first time Earth’s magnetic field has flipped. Such geomagnetic reversals have happened many times in our planet’s history, though not overnight.

New research into ancient Italian lake sediments shows Earth’s last magnetic reversal 786,000 years ago occurred in less than 100 years.
