  1. Mar 31, 2012 #1
    1. The problem statement, all variables and given/known data
    You are holding a conducting loop of copper and looking at its circle. Behind it is a long current-carrying wire carrying the current from left to right. As you pull the loop toward you, what is the direction of current flow if any?

    A)No way to tell
    B)Counter-clockwise
    C)the applied field is tangent to the loop
    D)Clockwise
    E)None at all


    2. Relevant equations
    emf=-d(magentic flux)/dt

    Not too sure what to do here....

    Welcome to PF, kimberlyann9! :smile:

    What can you say about the direction of the magnetic field?

    And how would you normally calculate a magnetic flux?
