The composition of the spinning outer core of metallic liquid, which is thought to be part of the origin of the Earth's magnetic field, is primarily composed of iron and nickel. Therefore, the correct response is:
C iron and nickel
Magnetic fields are produced by the motion of electrical charges. The motion of negatively charged electrons create the magnetic field in a bar magnet. The origin of the Earth's magnetic field is not completely understood. It is thought to be associated with electrical currents produced from the coupling convective effects and rotation of the spinning outer core of metallic liquid.
