Source of the Earth’s Magnetic Field
C Johnson, Physicist
This concept was conceived and Engineered by March 1996. This presentation was first placed on the Internet in June 1997.
A rather simple and possibly even obvious explanation seems available to explain essentially everything about the immensely complex and peculiar magnetic field of the Earth. The traditional Dynamo Theory which has enormous masses of ionized iron atoms ROTATING WITH THE EARTH is shown to be clearly incorrect, but close. Instead, it is believed that PAIRS of COUNTER-ROTATING convective circulations inside the Core, where the net effect of the pair of iron circulations tends to cancel out at a large distance such as at the surface of the Earth. When slight variations occur in EITHER of the two convection circulations, the measured magnetic field at the surface of the Earth could rapidly become North-directed or South-directed, explaining the many Magnetic-Pole-Reversals that have been detected in volcanic rocks around the world.
Given the fact that two much stronger, opposed magnetic fields are then the source, there would then also be quadrupole and octopole components of the measured magnetic field, as well as the famous dipole, and they all can then vary in complex and even rapid ways. Such quadrupole and octopole components of the Earth’s magnetic field are well confirmed.
Left: No measured magnetic field; Right: Normal measured magnetic field
The discussion below will clarify these animations, where the outer circle represents the surface of the Earth and all the activity occurs within the Earth’s Core. Instead of a single circulation as in the popular Dynamo Theory, it seems certain that there are actually pairs or quads of counter-rotating convective circulations as shown here (both driven by the [red] hot-spot that is slightly off-center).
