Biot-Savart applied to rectangular coil

  1. Apr 26, 2010 #1
    1. The problem statement, all variables and given/known data
    A rectangular current-carrying coil, with side lengths a and b has N turns. The current, I is stable.
    The coil is shorter than its width. Calculate the magnitude of the magnetic field at the centre of the rectangle.

    2. Relevant equations
    The law of Biot-Savart (I think).

    3. The attempt at a solution
    Stupid (I know) - but I am unsure of what to do with the element of Biot-Savart, which concerns the radius.
    Perhaps I could divide the rectangle into 4 segments - calculate each segment:
    Bsegment = (mu o/4p )(I/R)(cosa +cosb )
    and then add them up?

    Please, please help me as it is part of a larger assignment involving the effect of a magnetic field on a current-carrying coil.
