Biot-Savart and a Rectangular Loop

  1. Oct 29, 2014 #1
    1. The problem statement, all variables and given/known data

    Consider the figure on the right. Wire 1 is oriented along the y axis and carries a current I1. A rectangular loop located to the right of the wire in the xy-plane carries a current I2. Find the magnetic force exerted by wire 1 on the top wire of length b in the loop labeled, "Wire 2" in the figure.

    2. Relevant equations


    Biot-Savart Law

    3. The attempt at a solution

    I'm not sure where to begin. I've never worked with a problem like this before, only the basic problems.

    Remember dF = i dl x B ?
    i = current
    dl =differential length expressed as a vector.
    For B try ampere's law. Forget Biot-Savart.

    Okay, I tried this. Does it look right?

    It's too late tonite for me to check it in detail but your approach is spot-on.
