Earth's Magnetic Field according to wikipedia.
The Simple Facts
Earth's magnetic field (and the surface magnetic field) is approximately a magenetic diphole, with one pole near the north pole (see Magnetic North Pole) and the other near the geographic south pole (see Magnetic South Pole). An imaginary line joining the magnetic poles would be inclined by approximately 11.3° from the planet's axis of rotation. The cause of the field is probably explained by dynamo theory.
Magnetic fields extend infinitely, though they are weaker further from their source. The Earth's magnetic field, which effectively extends several tens of thousands of kilometers into space, is called the magnetosphere.
The Earth's North Magnetic Pole is the wandering point on the Earth's surface at which the Earth's magnetic field points vertically downwards.


In the Eighteenth Century, a Swiss Mathematician, Leonhard Eular took the multiple spheres theory and replace it with a single hollow sphere that contained the sun 600 miles wide. He said the sun maintained heat and light for an advanced civilization that he said lived there.
During World War 2, Hitler sent an expedition to the Baltic Island of Rugen. A man named Dr. Heinz was said to point a telescope camera in the sky in an attempt to photograph the British fleet across the hollow interior of a concave earth.








Cyrus Teed suggested in his theory that as well as the Earth being hollow there were people who lived inside it. In the center of the sphere were the sun, which was half dark and half light which gave the appearance of day and night. He stated because of the dence atmosphere down there, people could not see the other side of the inner sphere. The 19th century mathmeticians could not fully disprove this theory based on geometry alone, since the exterior of a sphere can be mapped onto the interior with little trouble.
Edmund Halley was a brilliant English astronomer whose mathematical calculations pinpointed the return of the comet that bears his name. Halley was fascinated by the earth's magnetic field. He noticed the direction of the field varied slightly over time and the only way he could account for this was there existed not one, but several, magnetic fields. Halley came to believe that the Earth was hollow and within it was a second sphere with another field. In fact, to account for all the variations in the field, Halley finally proposed that the Earth was composed of some four spheres, each nestled inside another.
