Magnetic and Electric Field Lines

  1. May 12, 2008 #1
    1. The problem statement, all variables and given/known data

    Magnetic and electric field lines are visually defined by field lines. Give three points to explain how the field lines can be used to describe the characteristics of these fields.

    2. Relevant equations

    (Not sure if needed to describe) Fm = qvBsin0, Fm = IlBsin0

    3. The attempt at a solution

    Farther apart lines = weaker fields?

    Positive charge = fields radiate from a point charge

    At every point on line, direction of field is tangeant

    The equations are not necessary. Seems okay to me.
