Magnetic Force Question

  1. Jun 11, 2007 #1
    1. The problem statement, all variables and given/known data
    Quick Question, you know that if two wires are 1 metre apart, both are 10 m long, they both carry 1 A, and the magnetic field they are in is 5 T, you would do the following to solve for force:

    F=(4pi x10^-7)(1A)(1A)(10m)/2pi*1
    But what if the two wires are different lengths? If one was 10m long, and one was 9m long, would you use the 9m in place of L?

    2. Relevant equations
    B=(4 pi x10^-7)I/2*pi*r

    3. The attempt at a solution
