Homework Help: Injecting a particle in space (question, not math)

  1. Mar 7, 2005 #1
    Suppose a uniform magnetic field exists in a finite region of space. Can you inject a charged particle into this region from the outside and have it stay trapped in the region by magnetic force? Explain completely.

    Originally I thought no because i didnt think one could keep a charged particle in one area in space due to a magnetic force. I thought it could be injected but not held into space, but not sure of the reason

    What kind of motion does a charged particle in a uniform magnetic field describe?
