The earth’s magnetic field is not like a permanent ferromagnetic. It is generated by the “dynamo effect” of currents in the outer core, which tend to be chaotic in direction and intensity, and therefore not necessarily centered on earth’s physical center. By the way, according to dynamo theory, movement in an electrically conductive fluid can retain a magnetic field, and the earth’s outer core is liquid iron. The currents themselves are a result of the Coriolis effect of the earth’s spin, the same thing that causes ocean currents or the trade winds.

Totally agree. Thank you for the intelligent response.

What happens in a magneto type dynamo when the axis (fields) align and friction is decreased?
