iron and nickel are highly ferromagnetic metals. They are the main metals in the earth's core. The outer core is molten and the metals exist mainly in ion form. The molten outer core churns due to the rotation of the earth forming funnel-shaped hurricane-like structures. As the iron and nickel ions get span in the giant hurricanes, the numerous loops in the hurricanes act like electric currents. This consequently causes electromagnetic fields to form around these ‘hurricanes’.
Explanation:
Due to the enormous nature of the outer core and the giant hurricanes in this earth's layer, the electromagnetic fields formed extended outwards from the earth towards outer space. This field is most significant in protecting the earth from high energy electromagnetic waves from the sun. This radiation if it were to reach earth's surface would erode the earth’s atmosphere and cause genetic mutations to organisms on earth.
