# Flux Density at Certain Point?

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.

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 $$\int$$lbla (sin$$\Theta$$/r2)dl

3. The attempt at a solution

B=3 x 10^-7/.02m $$\int$$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?
