We thank Gary Glatzmaier for kindly providing an image of his geodynamo simulations to use for the MagWiki logo. A brief description of what the image depicts is given below (also courtesy of Gary Glatzmaier).
A snapshot from a computer simulation of the generation of the Earth's magnetic field (the geodynamo). The 3D field is illustrated with magnetic lines of force, which are colored blue where the field is directed inward and gold where it is directed outward. The rotation axis of the modeled Earth is vertical in the image. The field is much more intense and complicated inside the Earth's fluid core where it is generated. Outside the core the field has a dominantly dipolar pattern. The computer model was developed and run by Gary A Glatzmaier (University of California, Santa Cruz) and Paul H Roberts (University of California, Los Angeles).
