Is an isolated electric field w/o its megnetic component emitted by household wiring?

Is an isolated electric field w/o its magnetic component emitted by household wiring ?

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 ?

. 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.

Update:

doesnt anyone get it ? I am talking about the separation of the magnetic field and the electric field. If two conductors are carrying a current in opposite directions, the magnetic field is SUPPRESSED, ie., N to N, and S to S. This arrangement will suppress the magnetic component but it does not suppress the electric field componernt according the field geometry. This is my contention and I want to verify this. The electric field surrounding a wire is at right angles to the wire and away from it and therefore cannot be self suppressing, see ? Do yiou agree with this postulate ? If you do not agree with it. then please explain why and how !!

    Both an electric and magnetic field are vector fields. Any vector field which is generated by two sources (two wires in your question) will be reinforced if each source generates the field in the same direction (simple static fields) and in the same phase (for the oscillating fields). This is called "the superposition principle". Since it applies equally to a magnetic and electric field it is not clear why you call one of the two fields "self-suppressing". I haven't seen this term applied to a vector field.

    NOTE: Your statement: "This means the intention in household wiring is to suppress the magnetic field." is not correct. "The intention" is to connect all the devices in parallel in the most economical way.

    i've got faith you have this quite backwards. evaluate the magnetic field as a around course around the twine, the place you should use your 'suitable hand rule' to understand the sector path. in case you align your thumb interior the path of modern pass, then the sector is orthogonal (suitable angles) to the present and can wrap around the twine interior the sam path that your palms might curl. it is authentic that the present interior the wires might pass in opposite guidelines, yet this does not reason the magnetic field to be suppressed. particularly, the electrical powered field which would be set up is in certainty between the two wires, so radiation is constrained. The magnetic field might nevertheless amplify and fall down with regard to the under pressure pair as modern flows.

    household wiring isn't shielded in anyway a volt stick will work on tps cable so some emf is present. Flemmings right rules apply.
