Are the precession and nutation of Earth's core directly connected with precession and nutation of Earth's magnetic field if they are present?
If the magnetic field of Earth is generated in the core of the Earth can we deduce core's precession cycle by measuring the precession of Earth's magnetic field (not Earth as a material object) or the ...

Do we need to know Earth's magnetic field locally?
I'm a high school student and in our course we have elements of earth's magnetic field (dip and other stuff) that lets us know the value and direction of magnetic field at any point on the planet.
I ...

Being the Earth modelized as a big magnet (or solenoid), which would be the field intensity of such a model inside the solenoid or magnet axis?
This question has arisen from the Carl Friedrich Gauss’ statement that the Earth could be modeled, concerning his calculations about the earth’s magnetic potential, as a big magnet, himself having ...

Shape of Earth's magnetic field
Why earth's magnetic field is compressed on day side and extended like tail on night side, like this
I know that it's due to solar wind but not how that compression and extension happens.
