Naoshi Fukushima : ウィキペディア英語版 | Naoshi Fukushima
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.
