Reason for Earth's Magnetic Field....A mystery discovered partially !!

  

 Current Reasons/Theories related to Magnetic Field:

The simple reason is that earth's core is composed of  liquid conductors (molten metal...at very high temperature) due to hot metal core there is a ocean of free ionized electrons and movement of these electrons resulted in circular current flowing inside core such that magnetic field emerges from downward direction(Southward direction) and  enters back from upward (North Direction) so we can say that the current is moving clock wise when observed from top.

                                      

                                         

From above paragraph we know that current is flowing in clockwise direction , that means electrons would be moving in counter clockwise direction. This could be explained by counter clockwise rotation of earth observed from top. So it means electrons are moving in direction of  rotating earth. 

But according to me this explanation is partially wrong or lacks explanation..

As due to rotation of earth the heavier particles may stick to the circumference of earth and due to friction the heavier particles may continue rotation resulting in heavier particles rotating counter clockwise (here heavier particles are positive kernels), which means positive charge i.e. current is moving in counter clockwise but we know as per the current geo-magnetic position the internal electrical current must be rotating clock wise , which is contradicting my thought / explanation of moving charges due to rotation of earth.  

Possible Reasons for reverse movement of internal metallic fluids.

The reason might lie in the formation of earth where due to collision there might be internal moving cycle started of fluids and after the formation of crust the earths rotation might be started due to another big collision of semi-formed earth.

Future of Earths Magnetic field

According to me due to two opposite / contradicting movements of internal charges , there might be a SHM inside the internal earth metallic fluids , which might cause slow periodic changes in magnetic field, but the maximum change in the fields (angle of deviation ) might be around +90 degrees and -90 degrees unlike contemporary notion of complete switching between poles (angle of deviation= 180 degree). Actually my predictions of  future of earth's magnetic field might be completely wrong but the questions raised by me for explanations aren't mere predictions...
