Consider two parallel straight wires carrying electric current in opposite directions with the same magnitude of 2.0 A. The center-tocenter distance between the two wires is 5.0 mm. One wire is infinitively long and the other wire is 0.30 m long. Is the magnetic force between the two wires repulsive or attractive? What is the magnitude of the magnetic force between them? ( =4.8×10−5 )
