My senior project for high school is to prove that NASA can make their launch more efficient by adding electromagnets to launch. I was thinking just magnets lining a tunnel coming from underground that move the payload a lot like a maglev. My job is to make a model of this, and I'd like to make a real, working model. I will print out a tiny model of a rocket that I design myself in Solidworks, but when it comes to launch I'm stuck. Does anyone have any suggestions on how I can make a small magnetic launching system for my model? Thanks!
