Two high-current transmission lines carry currents of 25.0 A and 79.0 A in the same direction and are suspended parallel to each other 40.0 cm apart.

A) If the vertical posts supporting these wires divide the lines into straight 18.0 segments, what magnetic force does each segment exert on the other?

B) Is the force found in part (A) attractive or repulsive?
