  1. Nov 20, 2012 #1
    1. The problem statement, all variables and given/known data

    A DC is flowing through a conductor LK.

    2. Relevant equations

    Will there be a current in the frame ABCD, when:

    a) The current in LK will be switched on and off.

    b) The frame will not move relative to the conductor LK.

    c) The frame will be dragged to the right.

    d) The frame will be spun around the conductor LK, not changing the distance between the two conductors. (image part b)

    In all cases briefly explain your answer.

    3. The attempt at a solution

    remember - there will be a current induced in the loop if the amount of magnetic flux threading that loop changes.
