Homework Help: ED problem

  1. Jul 28, 2010 #1
    1. The problem statement, all variables and given/known data
    Is given two parallel conductors of equal and finite length [tex]L[/tex]. The distance between them is [tex]a[/tex]. On these conductors flow constant currents [tex]I_1[/tex], [tex]I_2[/tex] in same dirrections. If the line which connecting their centars built angle [tex]\alpha[/tex] whith dirrection of conductor find the force that the first conductor interract to second.

    2. Relevant equations



    3. The attempt at a solution

    In solution is force given by

    [tex]\vec{F}_{21}=I_2\int^{\frac{L}{2}+actg\alpha}_{-\frac{L}{2}+actg\alpha}dz\vec{e}_z\times \vec{B}_1[/tex]

    Why the boundaries are [tex]-\frac{L}{2}+actg\alpha[/tex] and [tex]\frac{L}{2}+actg\alpha[/tex]?

    Tnx for your answer!
