Naoshi Fukushima

Naoshi Fukushima (福島 直, Fukushima Naoshi, January 19, 1925 – June 25, 2003) was a Japanese physicist specializing in the near-Earth space environment.

[1] He served as Secretary General of the International Association of Geomagnetism and Aeronomy from 1975 to 1983.

[2] 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.
