Question
Three parallel wires carry currents as shown in Figure $6.40 .$ Find the force per unit length that wires 1 and 3 exert on wire 2.
Step 1
Since the currents in wires 1 and 2 are in opposite directions, they will repel each other. Similarly, the currents in wires 2 and 3 are in opposite directions, so they will also repel each other. Show more…

Three long parallel wires are 3.5 $\mathrm{cm}$ from one another. (Looking along them, they are at three corners of an equilateral triangle.) The current in each wire is $8.00 \mathrm{A},$ but its direction in wire $\mathrm{M}$ is opposite to that in wires $\mathrm{N}$ and $\mathrm{P}$ (Fig. 54 ). Determine the magnetic force per unit length on each wire due to the other two.
In Fig. $29-64,$ five long parallel wires in an $x y$ plane are separated by distance $d=50.0 \mathrm{cm} .$ The currents into the page are $i_{1}=2.00 \mathrm{A}, \quad i_{3}=0.250 \mathrm{A}, \quad i_{4}=4.00 \mathrm{A},$ and $\quad i_{5}=2.00 \mathrm{A}$ the current out of the page is $i_{2}=4.00 \mathrm{A}$ . What is the magnitude of the net force per unit length acting on wire 3 due to the currents in the other wires?
Two long parallel wires in vacuum are $4 \mathrm{~cm}$ apart and carry currents of $2 \mathrm{~A}$ and $6 \mathrm{~A}$ in the same direction. Compute the force between the wires per meter of wire length.
