# Problem: Two high-current transmission lines carry current of I1 = 1.23 A and I2 = 2.32 A in the same direction and are suspended parallel to each other with a separation of 0.560 m apart. The vertical posts supporting these wires divide then into straight 20.0 m long segments.  What is the magnetic force one segment exerts on another, direction and magnitude?
