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.

Scientists study seismic waves and magnetic fields to determine the composition and properties of Earth's core. They use data from earthquakes and magnetic measurements to infer that the inner core is solid iron and nickel, while the outer core is liquid iron-nickel alloy. Deep drilling and experimental simulations also provide insights into the Earth's core composition.
An alloy of solid nickel and iron, mostly.
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
Scientists think the Earth's core contains iron because of the planet's magnetic field. Iron is a magnetic material, and the Earth's magnetic field is generated by the movement of molten iron in the outer core. Additionally, seismic waves and the density of the Earth indicate a high concentration of iron in the core.
Scientists think Earth's core is made of iron because iron is a dense material, and it is abundant in Earth's crust. Also, studies based on seismic waves and Earth's magnetic field support the idea that the core is composed mostly of iron.

Scientists think that Earth's magnetic field is generated by the movement of molten iron and nickel in the outer core of the planet. This motion creates electric currents, which in turn generate the magnetic field that surrounds the Earth.
Iron is the primary element that makes up most of the Earth's core. It accounts for about 85% of the core's composition, with the rest likely being nickel in combination with some lighter elements.

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.
Scientists believe Earth's core contains iron because of the planet's density and magnetic field. Iron is a dense material that would sink towards the core during the Earth's formation. The presence of iron is also supported by seismic wave behavior and the Earth's magnetic field, which is generated by the movement of molten iron in the outer core.

Scientists believe Earth's core contains iron because it is consistent with the planet's overall composition and density. Iron is one of the most abundant elements in the Earth's crust and mantle, so it is likely to be present in the core as well. Additionally, the magnetic properties of the Earth can be explained by the presence of iron in the core.
