What creates Earth's magnetic field?
by

1 Answer

Answer :

Scientists think that the presence of the molten nickel iron layer of Earth's outer core and the spinning of the planet creates the magnetic field through the geodynamo mechanism.The geodynamo mechanism couples the convection of the liquid metal in the Earth's core with the magnetic field to create the current responsible for the magnetic field.Other planets with a molten metal core can also have a magnetic field.See related links.Earth's magnetic field is generated by the electric currents in the conductive material of its core.
