Hello, I do have an question about electromagnetic fields (EMF). Yesterday I conducted an small experiment after stumbling onto videos on YouTube about EMFs and the alteration of human biology. Those stunned me, because I had no idea electromagnetic fields could alter human physiology. On further investigation, I found a website listing outcomes of scientifical studies done upon EMFs, radio frequencies and so on. While reading the summaries of those studies, I remembered that everytime I had to plug in my stereo-speakers into my computer's audio jack, there was a buzzing sound coming of them. So with my fingers I touched the metal connector of the cable and the buzzing sound started. Well, I am of curious nature. Connecting the idea of amplifying electromagnetic fields (EMFs) - or at least I think the sound represents EMFs - I conducted myself to objects around me while still being connected to the audio device. * When touching my computer, the sound got quite louder and the frequency changed. * When touching my tablet computer, the sound got a bit louder and the frequency changed. Now up to here I could explain this (for me) phenomenom: My body picks up the electromagnetic field and changes it's vibration towards the more powerful field available, which seems to be the electromagnetic ones on direct contact. But then my explanation attempts came to an end, when I discovered the following: * When touching the side of my fridge, the sound got extremely louder * When touching the front of my oven, the sound got a bit louder * When touching the metal frame of my cooking ceramic glass cooktop, the sound got extremely louder * When touching radiator (central heating), the sound got extremely louder * When touching the plant next to me, the sound got a bit louder (All of the above changed sound frequency also) So how does one explain this? I am quite lost in searching for answers, because I do not know the scientifical / technical terms at the moment.
