Question
Two long straight parallel wires, carrying (adjustable) current I1 and I2, 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 I1 I2, would be :
