Iron is magnetic which forms the Earth's magnetic field.
They think that because the iron in the core has sort of a magnetic force to it. It helps to rotate the earth and is a very vital part to this earth's survival. If there was no core, there is no us.
The iron nickel core has been determined to actually exist from the examination of meteorites, from the gravitational field of Earth, and from the Earth's density in comparison to its volume.
Samples of Earth's crust contain less iron than found in meteorites, and iron is a comparatively heavy element that would have sunk into the planet when it was being formed.
