... Trapped Motion . ... The trapping of particles by magnetic fields was first studied by Kristian Birkeland in Norway, starting around 1895. ... Perhaps the most interesting story of that era concerns Nicholas Christofilos , a Greek elevator engineer whose avocation was the study of particle motion in magnetic fields. ... Atomic bombs produce large numbers of energetic electrons, and Christofilos hoped that such electrons would become trapped in the magnetic field as an artificial radiation belt. ...
