Homework Help: Flux Density at Certain Point?

  1. Jan 19, 2009 #1
    1. The problem statement, all variables and given/known data

    Someone else posted up this image on yahoo answers and my question is very similar except the numerical figures are different really.

    http://s3.supload.com/free/Picture_258.jpg/view" [Broken]

    How can i solve for for the flux density at the point using the 3-A current?

    2. Relevant equations

    B = I x 10^-7 [tex]\int[/tex]lbla (sin[tex]\Theta[/tex]/r2)dl

    3. The attempt at a solution

    B=3 x 10^-7/.02m [tex]\int[/tex]lbla (sin 90/2.52).07m

    I am no even sure if I am attempting this correctly. Everything I'm reading doesnt really explain the steps to get the answer. They give other examples that look nothing like my problem so I am lost as can be. Can someone help me out here?
