Why does the earth switch polarity?
Why does the earth switch polarity? The reversals take place when iron molecules in Earth’s spinning outer core start going in the opposite direction as other iron molecules around them. As their numbers grow, these molecules offset the magnetic field in Earth’s core. What does normal polarity mean? Normal polarity is defined as the magnetic […]
