Problem with conducting loop and magnetic field

  1. Oct 12, 2015 #1
    1. The problem statement, all variables and given/known data
    A rectangular conducting loop of wire is approximately half-way into a magnetic field B (out of the page) and is free to move. Suppose the magnetic field B begins to increase rapidly in strength. What happens to the loop?

    2. Relevant equations
    Not sure which ones are relevant and which are not, but it seems like this is more conceptual than algebraic.

    3. The attempt at a solution
    Not sure where to start on this one. I cannot seem to grasp electromagnetism in general, I've read and re-read the notes, and haven't gotten any closer to a solution. Could you guys give me suggestions on where to start to work towards the solution for this? Hate to ask to much, but could you also give me any suggestions for resources I can use to strengthen my understanding of electromagnetism in general?

    The Maxwell-Faraday equation governs what happens here. This is a good intro.
    I reckon that if you are mathematically inclined then learning Maxwell's Equations is the quickest route to understanding electromagnetism.

    What does Faraday's law say here? Induced emf? Resultant current? Then, the force on a wire or wires carrying a current in a B field?
    The answer is qualitative rather than quantitative but you should get the direction of motion (if any) right.
