the layer of the earth resposible for the earths magnetic field is the core which consists of the liquid core/outer core and the solid core/inner core.
The Earth's magnetic field is generated in the fluid outer core by a self-exciting dynamo process. Electrical currents flowing in the slowly moving molten iron generate the magnetic field.In addition to sources in the Earth's core the magnetic field observable at the Earth's surface has sources in the crust and in the ionosphere and magnetosphere.lectrical currents flowing in the slowly moving molten iron generate the magnetic field.
