One more note, that I haven’t seen pointed out here. Even if it was strong enough to be felt, things wouldn’t be attracted towards the wire. Electricity sets up a magnetic field in a circle around the direction of flow. So if the effect was strong enough to be felt you wouldn’t feel things attracted to the walls, you’d feel them try to pull along the wall with the effect getting stronger the closer you are to the wire.
When you coil wire you get an attraction towards the coil because of the coil shape and the looping. It creates a magnetic field that kind of looks like a doughnut looping things toward the center of the coil, making that an attraction point (assuming polarity matches blah blah blah).
