There could be two explanations. One that there is an induction from the other wires depending on how close the proximity of this wire is to the others. The second and most likely is that there is a resistive load separating it from the other wires. Shut the fence off and check the junctions where the wires are spliced to one another. Look for corrosion or a white powdery dust where the wires are spliced. Clean it up and see if that corrects the condition.
Not usually unless you go around licking grounded objects when you are touching live electrical circuits. The only time that you will receive a shock is when you become the ground return for the electricity to flow through. In effect you become the neutral wire that returns the current flow that is supposed to go back to the distribution panel.
You can test the horn unit by connecting one end of a wire to it and momentarily touching the other end to the battery positive post if the horn unit is grounded.
Objects must be grounded so that they do not fly around. If objects flew around they could break other objects or hurt people.
A grounded metal shield that is around a signal wire prevents outside electric fields from reaching the signal wire. This is because electrons are free to move in a metal and the electrons in the metals surface move in response to the outside electric field. Below the metal surface the electric field is canceled by the field created by the electrons that have been drawn to the metal surface by the outside field, which is the noise source. Since the signal wire is within the metal cage it does not receive the noise.
It turns into Magnet.
Abilene Texas is a deregulated city. That means you can choose your electric company. Go here and input your address and receive the rate for that area. http://cheaptexaselectricrates.com
The electric field around an electric charge varies inversely as the square of the distance to the charge.
If your Hot wire is shorted to ground and the breaker won't reset you'll need to disconnect whatever is on the circuit until the problem goes away. This will be impossible to do without tools. You might be able to hear an arc as the shorted wire trips the breaker, but that is a long shot. You may be able to see some evidence of charring or what appears as black soot around an outlet or light fixture.
Nothing happens. The wire will still conduct electricity. An example of this is the overhead utility wiring. The insulation on a conductor is there strictly to keep the conductor from touching any thing that would ground the conductor. This grounding could be from another adjacent conductor or a grounded medium around the conductor. A grounded conductor will trip the over current protection and trip the circuit off line. Without an insulation on the wire multiple wires in a conduit could not be utilized.
It's the electric field.
