It is attracted, just very weakly.

An analogy for this might be if you had asked “If feathers supposedly weigh something, why didnt I notice there was one in the box of books I was moving?” The error in that question is probably obvious. Of course a feather weighs *something* it’s just incredibly light and not noticeable by a person among other things.

The magnetic fields around household wiring are similarly weak as a feather is light. It’s attractive to metals, but so little you’d never notice. You could put that feather on a scale or hold an EMF detector next to a wire and in both cases you’ll get a clear reading. It’s just not strong enough to feel with your hands or whatever.
