Magnetic Attraction: Exploring E&M Wire Interactions

[QUOTE="PhysicsInNJ, post: 5458195, member: 577483"] Apologies if this is being posted in the wrong section! this is just a side thought I came across, it is not HW. In learning about magnetism, I know that a changing current in a wire creates a magnetic field. So why are wires in our homes/ anything with wires close together not constantly attracting or repulsing each other? At first I thought this was because they are not changing except when turned on/off which is such a small amount of time that the B field is negligible. But then I remembered that most homes have AC which is constantly changing anyways. [/QUOTE]
