A computer simulation of the magnetic field that scientists expect to form in the Madison Dynamo Experiment. As intended, the predicted magnetic field shows a striking resemblance to the Earth's. The transparent sphere in the center represents the experiment's model of our planet: a stainless steel vessel containing a ton of molten sodium metal. The shaft coming in from the left is one of two, which together turn the propellers that stir the sodium.
