Two long straight parallel wires, carrying (adjustable) current $I_1$ and $I_2$, are kept at a distance $d$ apart. If the force $'F'$ between the two wires is taken as 'positive' when the wires repel each other and 'negative' when the wires attract each other, the graph showing the dependence of $'F'$, on the product $I_1 I_2$, would be
