Hello I'm a student and I have conducted an experiment where I buried a wire underground. Since there are many underground conductors in Seoul(where I live), I've always thought whether metal substances from the earth would effect the conductor's transmission. If the magnetic fields of the substances could interfere the underground conductor's current, there must be a loss of electricity.
Therefore, I actually buried 10 meters of a wire nearly 40~60 centimetres under the ground and observed if there was any difference in voltage or ampere. As a result, the voltage actually dropped a little(about 0.475V). How could this be? and if I'm right, how could we prevent this from happening? Please share your opinions.
