Hypothesis : This is said to be a knowledgeable guess in the field of sciences.
Observation : The scientist engage in thorough study or observation of the experiment or facts he wants to establish.
Experiments : The scientist engage in series of experiments to back up his fact and observation.

It must pass numerous scientific investigation and often involving contribution from well meaning scientist in that domain. The theory must be simple , precise and express-able so it can be repeated by other scientist. This established fact should not contradict previous principles or theory but instead expand and agree with others.
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
