Wire Loops, Current, Magnetic Field, & Straight Wire HELP!

  1. This problem deals with current and the magnetic fields of these wire loops & straight wires. The question is listed below, as is the link to the picture. Thanks SO Much for your help!!!


    If that one doesn't work, try this one:

    In the diagram, one current flows through the straight wire and another current flows around the wire loop, with the magnitudes shown. What are the magnitude and direction of the force exerted on the wire loop by the current in the straight wire?
