Ar. Prasanna et S. Sengupta, CHARGED-PARTICLE TRAJECTORIES IN THE PRESENCE OF A TOROIDAL MAGNETIC-FIELD ON A SCHWARZSCHILD BACKGROUND, Physics letters. A, 193(1), 1994, pp. 25-30
Trajectories of a single charged particle in the presence of toroidal
magnetic fields superposed on the Schwarzschild background geometry ha
ve been obtained, and it is shown that the toroidal field repels the p
articles and in particular the incoming ones get ejected in jet-like t
rajectories.
