What is the duration or duty cycle you are seeking? Same off and on, in other words a true symmetrical square wave? And what is your voltage source? For example, here is a simple square wave low power
It's what we call a color organ. At your level you may want to build a kit and if necessary modify it to suit your special purpose. Here is one example with its own video to give you and idea of what
I just don't know about the substitution. It is out of my range of experience and study. My opinion is that trying those other metals you mentioned represents an area for advanced study but not yet
These are all good questions and you are smart to think about it. I am not a physicist or chemical analyst so I cannot help you academically. I don know that there is more than just having 4 electrons
You are correct that the size/diameter/gauge of the wire is important. As is, too, the number of turns. The number of turns will determine the output voltage per rpm. The gauge of the wire determines
