Understanding Earth's Magnetic Field

neutron_p writes "Researchers from the University of Maryland's nonlinear dynamics and chaos research group are seeking to solve a major scientific mystery: How is the Earth's magnetic field formed and what causes changes in the field? To find answers, they are recreating on a small scale the forces that produce Earth's own magnetic field. Scientists have constructed a series of "geodynamos" - metal spheres filled with liquid sodium that emulate conditions of the Earth's spinning, churning molten iron core. This project involves more than 14 tons of sodium metal and a 10-foot stainless steel sphere."

    Wow! I ususally don't reply to followups, but I HAVE to ask you some questions.

    Are you certain there is no connection between ozone and the earth;s magnetic field?

    Are you certain there is no connection between the loss of ozone in the upper atmosphere and the increase at ground level (due to human activity?)

    And you are incorrect about the constituency of ozone: Ozone, according to my understanding, IS dissociated oxygen -- that is, an unbonded, single oxygen atom instead of a pair forming a molecule.

    Ozone is O-sub-1 and oxygen is O-sub-2.
