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

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]^{lb}_{la}(sin[tex]\Theta[/tex]/r^{2})dl

3. The attempt at a solution

B=3 x 10^-7/.02m [tex]\int[/tex]^{lb}_{la}(sin 90/2.5^{2}).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?
