Constants Two high-current transmission lines carry currents of 29.0 A and 71.0 A in the same direction and are suspended parallel to each other 45.0 cm apart.

If the vertical posts supporting these wires divide the lines into straight 20.0 m segments, what magnetic force does each segment exert on the other?
