Diggester writes "The ID24 beam line at the European Synchrotron Radiation Facility (ESRF) will use X-ray beams to subject iron and other materials to extraordinary temperatures and pressures. How the X-rays are absorbed should give insight into the mysterious processes going on at and near the Earth's core. For example, the work could unravel why the Earth's magnetic field can "flip"."
