Homework Help: Magnetic Fields

  1. Nov 14, 2005 #1
    The north and south ends of two magnets are placed facing eachother so that they create a uniform magnetic field. A small metal object passes through the field with a constant velocity. Sketch a graph to show how voltage varies with time for the path of the object from t=0 to t=3
    t=0 object starts moving, t=1 object enters field, t=2 object reaches end of field, t=3 object moves away from field.
    Repeat for if the object was accelerating.
    Sorry, i know this may be vague and non-sensical but i have a diagram and dont know how else to describe it.

    I thought that the object would act as a moving magnet therefore induce a voltage, but I really dont know where to go from there. Any help would be much appreciated.
