Why is the following situation impossible?

  1. Apr 1, 2013 #1
    1. Why is the following situation impossible? Two parallel copper
    conductors each have length , L = 0.500 m and radius
    r = 250 mm. They carry currents I = 10.0 A in opposite
    directions and repel each other with a magnetic force FB =
    1.00 N.




    2. Relevant equations



    3. Im thinking that it would be impossible since the magnetic field would cancel. is this right?

    no they would not cancel

    I think i need help understanding if this is two long parallel conductors or is it a circle?

    opposite current carrying rods repel each other
