Part 1:
In order to show that the following theory merits attention, and that the laws of electricity and magnetism are accurately described herein, I preface this theory with the fact that I spent my civilian career as a high school physics teacher, and later as an electronics engineer, both of which fields involve the principles and applications of electricity and magnetism.
Imagine that you submerge the candy ball of a lollipop in the center of a cup of coffee, and you slowly spin the lollipop stick between the palms of your hands. In this case, the candy ball rotates, but does not revolve, because it remains centered in the body of liquid. In your mind's eye, notice that the coffee swirls smoothly and evenly around the inside of the cup, without making waves. This analogy of a lollipop rotating, but not revolving, at the center of a cup of coffee, serves as a model of Earth's core, which is comprised of a solid spherical metal inner core rotating at the center of a spherical cavity filled with swirling molten metal, deep within the Earth.
Now, as with all metals, this molten metal outer core is a good electrical conductor, meaning that the iron atom, and the atom of other combined metals, possesses electrons in the outer valence band of the atom which are loosely bound to the nucleus at the center of the atom. Therefore, these loosely bound outer valence band (orbiting) electrons can easily migrate away from the nucleus, and can be conducted along a pathway within the body of the metal by flowing from atom to atom, sort of like a chain of billiard balls, which, when the first ball is impacted, it receives kinetic energy to impact the next atom in the chain, which then receives kinetic energy to impact the next atom, and so on.
We see this phenomenon every day, around the world, as electrons flow through conductive copper wires to illuminate light bulbs and to give sparkling life to TVs and all sorts of electronic devices.
Now, there is a well recognized principle of the field of physics which states that a moving electrically charged particle, such as an electron, will generate an electromagnetic field which encircles the path along which the charged particle is traveling -- sort of like a dog leaping out of a swimming pool and shaking off water as it runs away. The dog is analogous to the electron, and the spray of water encircling the dog's path is analogous to the encircling electromagnetic field generated around the path of the moving electron.
We see the application of this electromagnetic effect every day, around the world, in the operation of the common electric motor, in which electrons are voltaically energized to flow through a copper wire which is situated near a permanent magnet. In one direction of electron flow through the copper wire, the generated electromagnetic field encircles the length of wire in a specific revolving direction (let's say, in a clockwise direction). As this electrified length of wire is near one of the poles (let's say the north pole) of the permanent magnet, the wire's generated electromagnetic field will joust with the magnetic field of the permanent magnet to either physically pull the wire toward the north pole of the magnet or to physically push the wire away from the north pole of the permanent magnet. By reversing the direction of electron flow back and forth through the wire, there occurs a push-pull action which draws the rotary-mounted electrified wire to the the north pole of the permanent magnet on the rotational approach to the magnet, and then pushes the passing rotary-mounted electrified wire away from the north pole of the permanent magnet on its rotational departure from the magnet. Thus, the rotary-mounted electrified wire rotates the center shaft on which the wire is mounted, and now you have mechanical rotational energy to turn a fan blade, a food blender blade, etc.
Now, returning to our visualization of Earth's smoothly swirling molten metal outer core, we realize that the free electrons within the metals of the smoothly swirling molten outer core are as the free electrons which are motivated through the pathway inside a length of copper wire. Now, visualize the wire being formed into a horizontal circle, sort of like a hoola-hoop, with the free electrons racing as in a circular racetrack. This same generating of electricity occurs within Earth's swirling molten metal outer core. Naturally, the electrons circulating inside the swirling core generate a powerful electromagnetic field which encircles that molten metal hoola-hoop as if the hoola-hoop were threaded through numerous rings. It is the combined electromagnetic rings encircling the circular swirling molten core, aligned in a north-to-south orientation, which constitutes Earth's magnetosphere.
I hope to continue with this theory in a day or two.
