The EM field of a magnet or electromagnet can be converted to electricity with the use of a transformer (coil). My question is... Does that hold up for the whole EM spectrum... IR through Gamma?
That is similar to a transformator - you use alternating current to generate an alternating field, and this can be used to light lamps.Ok, I thought that I once saw a prof use a tesla coil, and a flourecent bulb to show that em fields were all around. Maybe I was mistaken.
