If a wire carrying current produces magnetic field around it, why its not attracted to nearby metals ? In a general household.

Yes all current through copper creates magnetic fields; but here’s the key; the field of a single straight wire with AC is too small to be seen as having an effect.
As the previous poster said, AC switches positive-negative so fast it has a net zero effect. AC also doesn’t like coiled lines, we call this inductance; the coiling of a wire creates a stronger magnetic field and when you try to run AC through a coil, the AC meets resistance in the form of the magnetic field.
Coiled DC current has a constant effect and little resistance to the flow of current.
I hope I did this right, thanks.
