Homework Help: Magnetic field rather than electric

  1. Sep 17, 2005 #1
    Magnetic field rather than electric....

    Ok here's my question.

    Why are magnetic fields used to deflect an electron beam rather than electric fields in television screens?

    I'd appreciate a substantial prod in the right direction.
    Feel free to give the answer though. :tongue:

    Maybe, but that's what the question asks......

    This is just a guess but is it to do with the voltage being harder to reverse in an electric field than the current is in a magnetic field?

    I find it hard to believe that noone can help me.
    Maybe I should've posted this somewhere else.....
