Penning Trap Question

  1. Sep 29, 2010 #1
    Hi I realize that this is probably not going to be a well known topic. However does any one know what actually causes the axial oscillation of a charged object (ion) in a Penning trap. I know that it is a result of the potential at the end caps. But the 2 end caps have a zero potential between them. Why does it oscillate ? Is it because it is getting attracted to one end cap then the other, which creates an oscillation?
