Currents in the outer core which has a high metallic content. these currents are likely to be convection currents ordered by the Earths rotation around the sold inner core. This generates a magnetic field as a homogeneous dynamo generating a self sustaining magnetic field.

The magnetic field comes from the Earth's molten interior.

yup
as the rotation of the hot liquid metal core causes metal to move against itself, and it creates an electric charge, which in turns creates a mag field.
strangely enough this field helps boost the electric charge even more, strengthening the mag field.
its a beautiful dependency.

The Earth's molten Iron core, baby!
So, i got a thumbs down because I was creative with my answer.
Lighten up.
