Question

What is Force between Two Parallel Current Carrying Conductors?

Answer

Force between Two Parallel Current Carrying Conductors - When two long straight conductors carrying current I₁ and I₂ are placed parallel at a distance of a from each other, then a mutual force of attraction acts between them which is given alongside. Force per unit length, F/l = μ₀/4π×2I₁ I₂/a N/m
