Earth's Geographical history repeats itself; Earth’s magnetic poles should ultimately swap places. The Earth’s magnetic field surrounds our planet like an invisible force field protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this field is continuously changing. Indeed, our planet’s history includes at least several hundred global magnetic reversals, where north and south magnetic poles swap places.
I found that the magnetic field from the Earth could be 'loaded up' by the magnetic fields of the Sun:

1) It solves the polar field theory of the Sun and the complete sunspot theory
2) It could solve the mystery of the magnetic field of the Earth
Astronomy is ruled by gravitation theories. However, there is currently no theory to combine gravitation and rotating oscillating magnetic fields. This theory will revolutionize an immense amount of physical theories and has far reaching consequences. For instance the presented theory in this document uses the effects of the rotating magnetic fields of the Sun in order to calculate the Sun's connection with the interplanetary magnetic field (IMF). By putting the mean length of these oscillating fields and the gravitation theory in an algorithm, we find a minimum and maximum interplanetary orbit of 234 to 596 days. But there is a lot more… The combined theory uses the effects of differential rotation in order to calculate the Sun's poloidal magnetic field strength. With it you can calculate at least (!) 12 basic functions of the sunspot cycle. They are related to-but independent from the formation of sunspots.
The change of the magnetic polarity is a result of the geo-magnetic dynamo cycle. This dynamo operates in the Earth core. Coronal Mass Ejection (CME) is solar plasma. When it comes close to Earth it interacts with the geo-magnetic field. But, this event cannot cause such global change like the polarity swap.
