On average, approximately 94% of the measured field is generated by a self-sustained dynamo in the fluid ion core inside the Earth, at 3000 km depth. Another approximately 3% is due to magnetized rocks in the upper-most 10-30 km of the Earth. Finally, the last approximately 3 % is due to electric currents flowing in the tenuous plasma of the upper atmosphere and magnetosphere. From Therese Moretto Jorgensen, National Science Foundation:

Thank you for sharing the information with us. So what is the relationship between the Earth's core and the magnetic field? This sounds like a great symposium.
