magnetostatic force due to the big magnet inside the earth (and not probably by the electric current of the above mentioned electrons moving along with the earth rotation) a motionless compass must be oriented in the same direction as a compass in motion.
(It seems that to observe such an effect our compass should be
either more sensitive than what the present compasses are or in a very fast motion (probably even more than the speed of the planes). Perhaps observed disorders in compasses of spacecrafts when being launched are because of this effect.)

Doug suggests that the free electrons distributed toward the surface of the molten core of the earth might indeed be pushed out to the equatorial region by the action of electrons in the presense of the magnetic field of the earth. In fact the electromagnetic theory predicts that if the free electrons are along the magnetic field line of the earth as shown in the following figure, the force exerted on them is inward as shown by relevant arrows in the figure. This means that electrons gather at the equatorial region and this itself helps the produced magnetodynamic field to be more intense.

In a similar way we should expect that the positive ions of the core to tend to gather at the poles of the core sphere in the presence of the geomagnetic field (while neutral atoms of non-ferrous substances of the core replace them at the equator of the core sphere). These suggest that we can ideally consider the distribution of the separated electric charges of the core as a negative ring of the core's equator and two positive poles of the core's geographical poles. Such a distribution has an electrostatic field originating from the earth's poles and ending up the earth's equator. Such a field is more intense at the poles than at the equator. Maybe this electrostatic field can be detectable by proper instruments and maybe it has its own effects on aurora borealis and australis.

It is an extreme simplicity to think that the orbit of revolution of the earth about the sun and also its direction of rotation about itself have not been changed during the long life of the earth, since eg it is notable that accurate measurements show some continuous changes in the length of time of one rotation of the earth. If we accept the existence of several changes in the direction of the earth rotation during its life, we can easily justify the proved inversion in the magnetic field of the earth by considering the above mentioned discussion about the relation between the direction of rotation and the direction of magnetic field.

Anyway, the process of slowing down of the earth rotational speed is not deniable. On the other hand the decrease of the earth magnetic field strength during the last 100 years has also been proved (and even it is known now that the next change in the earth geomagnetic direction is possible). And interesting to say that the simultaneity of these two decreasings (of the earth rotational speed and of the earth magnetic field strength) is a decisive evidence to prove the theory.

This theory also necessitates that, as there are some indications, the geomagnetic field has been passed through zero when reversing.

It is also possible that the changes in the direction of rotation of the earth have had their mechanical effect on the movement of the plates of the earth's crust.
