Griffiths 7.45

  1. Apr 25, 2008 #1
    1. The problem statement, all variables and given/known data
    A perfectly conducting spherical shell of radius 'a' rotates about the z-axis with angular velocity [itex]\omega[/itex] in a uniform magnetic field [itex] \mathbf{B} = B_0 \hat{\mathbf{z}}[/itex]. Calculate the emf developed between the "north pole" and the equator.


    2. Relevant equations



    3. The attempt at a solution
    I don't understand how emf makes sense in this context. I have only seen emf in currents. The emf is defined as an integral around a LOOP:
    [tex]\int_{loop} \mathbf{f} \cdot d\mathbf{l} [/tex]
    I don't see how you would generalize it here.
    I already read this https://www.physicsforums.com/showthread.php?t=112819.
