There was something I was going to try based on things I learned in different science courses last school year but I'm not sure if I would be sure enough of what I'm doing, and there's some things I'd like to ask here first. My idea mixes electromagnetic induction with electrolysis of aqueous solutions, but that would mean I'm asking for things related to chemistry and things related to physics. What would be a good approach to take, should I ask these things separately in the separate boards or is another board (like general) a good place to put it?

Stick it in General Science, and we can move it later for you if necessary.
