Homework Help: Magnetic field two parallel wires

  1. Oct 15, 2008 #1
    1. The problem statement, all variables and given/known data

    Two parallel wires are separated by 5.30 cm, each carrying 2.5 A of current in same direction. What is the magnitude of the force per unit length between the wires?

    2. Relevant equations

    B2=(mo constant)I2/2pid

    3. The attempt at a solution
    plugged 2.5 in for I and .053 for d
