Two long, straight, parallel wires of length 3.6 m carry parallel currents of 3.2 A and 0.9 A.
(a) If the wires are separated by a distance of 3.2 cm, what is the magnitude of the force between the two wires?
N
(b) If the currents are in opposite directions (antiparallel), how do the answers to parts (a) change?
(c) What is the magnitude of the force between the two wires?
N
