Perhaps my expression was not good enough. Let me rephrase the question: Are actuel the North-South directions of the magnetic fields and the pseudo vectors of rotations (right thumb rule) of the planets and of the sun too all the same (parallel or anti-parallel)?

They are not related and frequently change completely and independently. In the case of the Sun, every 10-11 years, in the case of the Earth, every few hundred thousand years.

@RobJeffries What is the actual situation of the planets of our sun system? How the rotations and the magnetic fields are related (right thumb rule for the rotations directions and north-south direction along the rotation axis, are they parallel or antiparallel?).
