Homework Help: Magnetic flux

  1. Feb 18, 2008 #1
    1. The problem statement, all variables and given/known data

    A rectangular loop of wire is moving toward the bottom of the page with a speed of 0.023 m/s (see the drawing). The loop is leaving a region in which a 2.5 T magnetic field exists; the magnetic field outside this region is zero. During a time of 3.0 s, what is the magnitude of the change in the magnetic flux?


    2. Relevant equations

    3. The attempt at a solution
    i have no idea where to begin. i thought that the magnetic flux was 2.5 because that is the change in b field but i know that isn't right.
