Homework Help: Electromagnetic Induction

  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
    C)the applied field is tangent to the loop
    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?
