does household wiring emit an electric field?
Household witring is doubled and hence the magnetic field component of the current is suppressed. Is the electric field component also suppressed or does it radiate into the local space ?
Ok, but I want to emphasize the question - if the electric field can be divorced from ther magnetic component... The current flows in the AC wiring is doubled and in OPPOSITION, hence the two magnetic fields generated by the two wires will mutually suppress each other. This is unlike ther flow in a coil where the fields in the windings will mutually reinforce each other.
This means that the intention in household wiring is to suppress the magnetic field. However the electric field is not directionally organised as the magnetic field component , it is a right angles to the flow, away from the wire,. hence it is apparently not mutually self suppressing, but rather self supporting.. this is the point of the question. Since it is not apparently self suppressing then it would follow that it is free to radiate from the wire in full strength unlike the magnetic field which to repeat IS self-suppressing.
This is the essential question.

Yes, there is an electromagnetic field from house wiring. Any wire carrying an AC current radiates an EM field.
The cancelation is far from perfect. All EM fields have an electric and a magnetic component.

House wiring carries very low electro-magnetic wave at very low frequency 60Hz which cannot fly away from the wire like radio frequency. But it could be picked up at a very close distance like 1/4 inch and its field strength is very very weak because it has only 120V. Our body also can pick up this 60c/s field by coupling effect. You may test its existing if you have a high gain amplifier that has a microphone jack input. Taking a small pick of metal with bare hand then insert it into the phone jack input.A very loud Humming noise can be heart,that is the 60Hz sound like.

electric cutting-edge and electric magnet fields are continually latest jointly. the better the voltage the greater beneficial the magnetic container. Take a conveyable radio and turn it to a AM station and wave it in front of your electric outlet. you will pay attention the 60 Hz hum. force below a mains capability line with the AM radio on and you will pay attention the hum. that provides you a primary thought of the capability of the sector.
