Yes well it helps to be a little more specific than a teenage girl.

Whatever. Thanks. That is what I been saying for like years now.
Didn't read the article.Didn't need to..Ask ANY Master or LONG time J-man electrician about Electromagnetic fields around high voltage transformers & their unique ability to find the TINIEST grounded path within arms reach...
Thanks perki thats an excellent video. Even though the video is 10 years old it makes clear quantum physics, superconductors and electron manipulation are where the current science is. Electro-magnetics have been studied for literally a 100 years. Transformers are based on electro-magnetic fields, for instance. I think people forget audio is simply electrical signals operating at different frequencies.

EMF - electromagnet waves

AFAIK, electromagnetic field is just a magnetic field created by the flow of electric current while electromagnetic wave is the field that has enough energy to leave the wire and travel in space.
