Equation for the emf for a rotating loop

  1. Feb 9, 2010 #1
    1. The problem statement, all variables and given/known data

    Describe the way that the loop is facing for this value to be a maximum. What is the equation for the emf for the rotating loop?

    2. Relevant equations

    I dont know.

    3. The attempt at a solution

    I cant really attempt the problem without the equation. This is a virtual lab interactive and I have several peices of information happening:

    1) Voltage: Varies and Reaches a Maxima and Minima
    2) Peak Voltage: is constant at the maxima.
    3) Feild Type: Uniform
    4) Loop Radius: 50cm
    5) Loop Movement: Automatic
    6) Rotation Speed: 2.0 cyc/s

    Yeah, I just dont know the equation for an emf for a rotating loop, If i had that, I wouldn't be so stuck, ya know?


    Thanks for any help in advance.

    Would, Motional EMF be the equation that I am looking for?:
    [tex]\xi[/tex] = [tex]\nu[/tex] * B * L

    yes?

    Maximum EMF = ABω where A is the area, B is the field and ω is the angular velocity.
