Moving loop in magnetic field (concepts)

  1. Nov 3, 2008 #1
    1. The problem statement, all variables and given/known data
    In the figure, a region with constant (externally produced) magnetic field is shown. A wire loop moves into the magnetic field.

    [Image Included]

    Question 1While the loop is moving into the region with the constant external magnetic field, the magnetic field inside the loop due to the induced current in the loop points ...

    Question 2Which of the following is correct? While the loop is moving into the region with the constant external magnetic field, the magnetic force on the loop points ...

    Answer Choices
    ... into the page
    ... out of the page
    ... left
    ... down
    ... No magnetic field is induced by the movement of the loop.
    ... up
    ... right

    2. Relevant equations
    |e| = vBL (Not sure if it's relevant)


    3. The attempt at a solution
    For #1 I don't have any idea. For #2 I think that the force would oppose the motion, and therefore point to the left.

    Any help would be greatly appreciated! Thanks!

    You answer to question two is correct, apply the same logic to the first question.
