Homework Help: Find the force on each side of the loop

  1. Mar 6, 2008 #1
    1. The problem statement, all variables and given/known data

    A single-turn square loop of wire 2.00 cm on a side carries a counterclockwise current of .200A. The loop is inside a solenoid, with the plane of the loop perpendicular to the magentic field of the solenoid. The solenoid has 30 turns per centimeter and carries a counterclockwise current of 15.0A. Find the force on each side of the loop and the torque acting on the loop.

    2. Relevant equations

    B=unI

    3. The attempt at a solution

    I'm really confused about visualizing this situation, and figuring out what exactly their asking for. I guess that's my first problem.

    Hint: The magnetic field inside a solenoid is uniform. Just treat it as a region of space where B is constant.
