Homework Help: Mutual Inductance Between Square and Circle Circuit

  1. Feb 26, 2013 #1
    1. The problem statement, all variables and given/known data
    There are two circuits in the XY plane: one is a square (side 0.2 m in
    length) centered on the origin. The second is circle or radius r also
    centered on the origin. The circle is smaller than fits inside) the square.

    By assuming the radius of the circle is small compared to
    the length of the sides of the square, describe how you would estimate the mutual inductance between the two circuits. Also, describe how you would determine the magnetic field Bz due to the square circuit.

    2. Relevant equations

    There are several equations, but I'm not sure all apply..these include the Biot-Savart law, Neumann formula, etc.

    3. The attempt at a solution

    Okay so how I how to deal with the inductance of other basic setups like 2 loops etc. But I don't know how to go by a small circle circuit with a square. Any ideas?
