"Funny part is the electric industry still tries to convince us that the wires don't give off anything!" I think you misunderstood, they most likely meant the effects decease rapidly the farther you are away from the lines. In your house from wiring, appliances, your hair dryer, surrounded by electric fields. The higher the voltage of a power line the more powerful the electric field, but as I said dissipates rapidly with distance.
Sorry if I wasted anyone's bandwidth..guess some people just don't want to educate themselves...that said, get yourself a Gaussmeter and test YOUR own microwave or your electric blanket..just sayin.......Dennis

Fought the transmission lines that were going to be put up by my house for 2 years......learned more about Transmission lines than any human should ever know.....sold my dream home and moved.
It's called Stray Voltage. It is the nature of high powered Transmission lines.
They are required to ground the lines every 1/4 mile but they do not. There is complete written requirement statement on file for the power companies to follow called the "Findings of Fact" to ensure safety among many other items. It's about 6 inches thick. It's drawn up and NO ONE EVER reads it and/or NO ONE is assigned to read it, to see if they follow all the requirements.
That's how it works its their******shoot,if they don't follow each requirement the line costs them far less. And no one ever checks.
I got a copy of it and called them on each and every thing they did not follow for a couple of months. I was told I cost them a couple of millions of dollars, before I was instructed to stop or find myself waking up dead one morning. Fast forward 4 years and that entire transmission line is still NOT grounded, nor did they put up the bird deflectors to prevent the raptors from killing themselves as they migrate.
Grrr, don't even get me started! Be thankful you were not hurt or even killed from the stray voltage.

Hey, I was gonna say that! I think I got a brain cramp.

Inside a source of emf that is open-circuited, the conservative electrostatic field created by separation of charge exactly cancels the forces producing the emf. Thus, the emf has the same value but opposite sign as the integral of the electric field aligned with an internal path between two terminals A and B of a source of emf in open-circuit condition (the path is taken from the negative terminal to the positive terminal to yield a positive emf, indicating work done on the electrons moving in the circuit). Mathematically:
where Ecs is the conservative electrostatic field created by the charge separation associated with the emf, d? is an element of the path from terminal A to terminal B, and ‘·’ denotes the vector dot product. This equation applies only to locations A and B that are terminals, and does not apply to paths between points A and B with portions outside the source of emf. This equation involves the electrostatic electric field due to charge separation Ecs and does not involve (for example) any non-conservative component of electric field due to Faraday's law of induction.
In the case of a closed path in the presence of a varying magnetic field, the integral of the electric field around a closed loop may be nonzero; one common application of the concept of emf, known as "induced emf" is the voltage induced in a such a loop. The "induced emf" around a stationary closed path C is:
where now E is the entire electric field, conservative and non-conservative, and the integral is around an arbitrary but stationary closed curve C through which there is a varying magnetic field. Note that the electrostatic field does not contribute to the net emf around a circuit because the electrostatic portion of the electric field is conservative (that is, the work done against the field around a closed path is zero).

While the math was over my head, I do not feel you wasted my bandwidth. It's a shame there is always someone who resists learning.

Well, Dennis - you gave a five dollar answer and some only needed the two-bit version..
Don't see any birds -except the now extinct "Tingle Bird- sitting on high tension wires, huh!?

I always wondered what happened to the Professor and Mary Ann, now I know.
While Dennis tried to explain what was happening in terms we engineers understand, for the average lay person it is probably rather confusing.
In somewhat simple terms, anytime current flows through a conductor a magnetic field is produced around the conductor. The strength of the magnetic field is related to the voltage and current flow. When another metal conductor is placed within the magnetic field a current is induced into the other conductor. This is a simplified explanation of how the transformers you see on power poles work and also why certain objects placed within strong magnetic fields appear to be electrically charged.
There are also other phenomena that occur in relation to very hight voltages.

It isn't the magnetic field, it is the capacitive coupling of the voltage field through the air.
The current through a power line will be 3000A or less. I can tell you that you can stand right next to a 3000A AC wire at low voltage and not feel any effects, let alone 15 feet away.
