Which of these best scientists to study the generation of earth's magnetic field? a) comparison of rotation of the earth's core and crust. b) comparison of seismic waves in the earth's core and crust. c) examination of earth's outer crust. d) examination of the liquid mantle

The one that best help the scientists to study the generation of Earth's magnetic field would be : A. Comparison rotation of the earth's core and Crust

The Earth's magnetic field currently tilted at the angle of about 10 degrees with respect of Earth's rotational axis

hope this helps
