I just want to know where the electrons come from when a magnet passes through a copper induction coil. Do the electrons come from the copper coil itself( ultimately breaking down the copper over time), or is the electrons coming from the surrounding environment. If the electrons are coming from the surrounding environment could someone tell me where to find a published scientific experiment that supports that electrons are being "pumped" into the coil by the magnets? Why do generators go bad? Also, in a solar panel, are the electrons coming from the light energy hitting the material (light energy being absorbed and then given off as electrons), or is the light energy exciting and breaking off the electrons of the solar panel material (ultimately breaking the material down) Why do solar panels go bad? Thank-you so much. I think this will help me have an understanding of similarities or differences between electromagnetic energy and magnetism and electricity.
