As others have said, there is a weak magnetic field, but what I haven’t seen mentioned yet is that only a certain small set of metals are influenced by a magnetic field. In a household that will be ferromagnetic metals like iron (not stainless steel) and nickel, which don’t tend to be that common in modern houses (if you ignore nails, beams and some furniture). That said, without significant coiling, the effect is going to be almost negligible unless, perhaps, the cables are dangling right next to an iron beam.
