I have heard from here that if you put 1 turn of wire around your house, you can hear music all around inside your house. It doesen't tell me very much on all of the components etc. to drive but I am assuming that you have to have an amplifier on the receiver and the transmitter. To simulate, before actually performing the experiment, I wrapped 1 turn of wire around a cardboard box. For the transmitter, I found a stereo system, which can produce a very loud sound. The only problem is because it acts as a short, I can only turn it up to a certain volume. For the receiver, I just hooked up a speaker to a coil, and I heard a faint sound. I know with the scale of a large house, I will need some time of amplifier. How would I set up the circuit for amplifying the low signal sound found on the coil. Would this be possible with a TL082CP op-amp and if so, how would I set up the circuit? Also does anybody know of any better way of transmitting the sound through it or is the stereo fine for the setup around my house?
Also, I came across a very strange thing when I found a head-set and put one ear-piece in the magnetic field. I heard the audio out of the other. I had nothing connected up to the jack and it seems impossible for this to happen with a stereo head-set. Why is this happening?
