Answer
Brief Explanations:
The Earth's magnetic field is generated by the movement of molten iron and nickel in the outer - core. Iron and nickel are ferromagnetic materials. Movement of these conducting materials in the presence of a magnetic field creates electric currents which in turn generate the magnetic field. The outer - core is liquid and the inner - core is solid.
Answer:
Earth's core is composed of iron and nickel.
