Earth Magnetic polar flip 

A report by Adrian Dvir M.Sc.

The magnetic pole behavior is not a stand alone phenomena but a by product for a whole complicate system that is mainly affected by external to Earth natural influences that take place during the ages. The most stronger influence, although progressing very slowly is the ever changing speed of time caused by the local universe expansion. Time speed is influenced by the average density of matter. The total average matter in planets in a given volume of space. As this density drops the speed of time raise as a result of less interference of Gravitational slow down of the speed of time. 

The same system affects sub atomic particles and matter structures responsible to the magnetic field and result in slow oscillations. 

The Magnetic field is indeed going to decrease in intensity and eventually flip. When this will happen the resulting effects on life form of Earth is no so much related to the magnetic polarity change but to other more acute results of the changing of time speed. As already explained to Adrian in an Early article (Aliens speak about speed of time). The Changing of time speed is not a linear process. There are breaking points or anomalies points that may be very violent. It may manifest in the form of Earth quakes, floods, and violent weather and other strange effects.
