1) Is there any evidence that the Earth's magnetic field originates in the core rather than elsewhere? What, you mean like Cincinnati? 2) Is there a compelling physical model? Yes, there is. http://en.wikipedia.org/wiki/Earth's_magnetic_field Likes ProfuselyQuarky and davenn Jun 6...
As new crust is created at a spreading ridge, the cooling magma captures the intensity and direction of the magnetic field in “stripes.” A, b, and c represent the evolution of the ocean crust over time as it moves away from the spreading ridge. (Wikipedia Commons) One example of how ...

s magnetic field. This magnetic field extends outward from the Earth for several thousand kilometers, and creates a protective bubble around the Earth that deflects the Sun’s solar wind. Without this field, the solar wind would have blasted away our atmosphere, and Earth would be dead and ...
the Magnetic South pole is the location on the Earth's surface where "the direction of the Earth's magnetic field is vertically upwards." This forms a magnetic dip that is 90˚ at the Magnetic South Pole. This location moves about 3 miles (5 km) per year and in 2007 it was located...
