Question:

Two long straight parallel wires, carrying (adjustable) current $\mathrm{I}_{1}$ and $\mathrm{I}_{2}$, are kept at a distance $\mathrm{d}$ 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 $\mathrm{I}_{1} \mathrm{I}_{2}$, would be :
