Electromagnetic induction question

  1. Apr 23, 2015 #1
    I seem to have a fundamental misunderstanding of the principle here. Picture1.png
    in the previous part it was required to sketch the graph for the hall probe. I knew since the speed was constant the field was cut at a constant rate hence a straight line was needed. However I did not understand why it dropped off sharply towards the end.

    For the part shown in the image, I do not understand what is different about the coil graph from the probe graph. Surely the same logic applies, same rate of movement hence same EMF? Why would the coil be different?

    Look under 2. relevant equations to see what the emf is.
    What does a Hall probe measure ?

    (Uh-Oh, did you erase the template :)) ?)

    What do the induced emf in a coil depend on?
    Any law come to mind?
    Formulas?
    How is the magnetic field of the setup configured?
