# Homework Help: Equation for the emf for a rotating loop

1. Feb 9, 2010

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
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.
