The outer core is a layer of the Earth located beneath the mantle and above the inner core, primarily composed of liquid iron and nickel. It extends from about 2,900 kilometers (1,800 miles) to approximately 5,150 kilometers (3,200 miles) below the Earth's surface. The movement of the molten metal in the outer core generates the Earth's magnetic field through the dynamo effect. This layer plays a crucial role in geodynamics and the overall behavior of the planet's magnetic properties.

What layer of earth creates earth magnetic field?

The Earth's magnetic field is the result of electric currents in the liquid metal outer core.The outer core of the Earth is over 2,000 km thick. It sits above the solid inner core and is composed of highly conducting liquid iron and nickel. Above the outer core is the Earth's mantle.The geodynamo is the mechanism thought to be responsible for the electric current in the core and the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field.See related links.
