Fukushima Naoshi?, January 19, 1925 – June 25, 2003) was a Japanese physicist specializing in the near-Earth space environment. He served as Secretary General of the International Association of Geomagnetism and Aeronomy from 1975 to 1983. In 1990 he was awarded the AGU’s Waldo E. Smith Medal. He is best known for proving that, under certain conditions, the magnetic field from a field-aligned current and the magnetic field from the associated Pederson current in the ionosphere would exactly cancel at the surface of the Earth. The magnetic equivalence of field-aligned currents with Pederson currents is referred to colloquially as Fukushima’s Theorem. Fukushima’s Theorem holds that for all points beneath the ionosphere the magnetic fields from field-aligned currents and their corresponding Pedersen currents exactly cancel. By superposition the total magnetic field at the ground is then equal to the magnetic field from just the ionospheric Hall currents. The Waldo E. Smith Medal is given out by the American Geophysical Union to recognize “individuals who have played unique leadership roles in such diverse areas as scientific associations, education, legislation, research, public understanding of science, management, and philanthropy, and whose accomplishments have greatly strengthened and helped advance the geophysical sciences”. The award was created in 1982 and named after Waldo E. Smith, the first Executive Secretary of the AGU. The award is given not more often than every other year.[ supreme supremewidgets supremeauctiononlinesoftware.widgets.EbayGalleryZ. supremewidgets supremeauctiononlinesoftware.widgets.GalleryBasicFree. supremewidgets supremeauctiononlinesoftware.widgets.FeedbackWidgetBasicFree.
