Electric Currents in Geospace and Beyond

Electric currents are fundamental to the structure and dynamics of space plasmas, including our own near-Earth space environment, or “geospace.”This volume takes an integrated approach to the subject of electric currents by incorporating their phenomenology and physics for many regions in one volume. It covers a broad range of topics from the pioneers of electric currents in outer space, to measurement and analysis techniques, and th...
