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 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?
