Two long, straight, parallel wires of length 4.5 m carry parallel currents of 3.1 A and 1.1 A.
a) If the wires are separated by adistance of 3.4 cm, what is the magnitude of the force between the two wires?
b) If the currents are in oppositedirections (antiparallel), how do the answers to parts (a) and (b) change?
