Homework Help: Magnetic field rather than electric

    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?
