What two layers of the earth are responsible for the magnetic field

The center of the Earth is made up of two layers, the outer core and the inner core. The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field.

Earth's inner and outer core

Explanation:

The Earth's core features molten and hot conditions which helps to create a magnetic field

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
