The goal of this presentation was to work through an interactive simulation of the earth's geomagnetic field interaction with the solar wind. In the interior of the earth circulates molten iron created currents that can be modeled approximately by current going through a loop. This produces a magnetic field around the earth that protects it from harmful ionizing radiation (solar wind). In the simulation, the solar wind was approximated by a stream of charged particles, and the magnetic field of the earth was approximated by that of a magnetic dipole tilted at 12 degrees angle from the sun. The lorentz force deflects the charges into a pole of the dipole, where it shows some spiraling that would normally lead to Aurora.
