Magnetic fields and 2 parallel conductors

  1. Dec 1, 2008 #1
    This question was on my homework and I don't really understand how it has to do with magnetic fields.
    1. The problem statement, all variables and given/known data
    As 2 parallel conductors with currents in the same direction are moved apart, their force of
    A) repulsion decreases
    B)Repulsion increases
    C) attraction decreases
    D) Attraction increases

    2. Relevant equations

    3. The attempt at a solution
    They will attract b/c I used the right hand rule and the 2 forces coming from both conductors are pointing towards the other. And I think it will decrease b/c the force of mag fields depends on magnetic field and the farther away the weaker so if magnetic field decreases then Force will decrease. So I think the answer is C. Not sure if its right.
