How closely do the magnetic fields generated by geodynamos align?

[Hornbein]

Here on Earth there are three major geodynamos that generate the magnetic field. My question is about how they interact. My guess that while the axis of rotation of each field is different, the fields they generate tend to align. My further guess is that they do so only partially so that in the vicinity of each dynamo the direction of the field is somewhat different. Is that right, and roughly how strong is the alignment tendency?

This is more of an Earth sciences or astrophysics question but I don't know where to go for such things so I'm taking a shot here.

Interesting, I didn't know that. Do you have a link where I can learn more about the 3 mechanisms? Thanks.

Ohhh ??
you have some scientific references for that ??
