# [Physics] Magnetic effect on AC circuits

electric-circuitselectric-currentelectricityelectromagnetism

We know that when currents in two wires move parallel to each other, they attract each other and if they are moving anti-parallel to each other, they repel each other but we cannot observe this in our daily routine; why?

I know this experiment is based on DC circuit and we cannot observe this in electric transmission lines because in our homes we usually use AC.

But what is the actual reason behind that we cannot observe an attractive or repulsive force in daily circuits? If actually it is because of AC currents, then why does AC current not show magnetic effect?

Usually, conductors run in pairs, with a fixed distance (insulator) between them. Such a configuration prevents you from noticing the force between them. Note also that the force is not large - $2\times 10^{-7}~\rm{N}$ for two wires that are 1 m apart and carrying 1 A of current. Which makes it hard to notice unless the currents are very large, or you set up a sensitive experiment.
