Hello PF! I am about to conduct a physics experiment to write my high school level paper on. I initially was going to investigate the Gaussian Gun, but my physics teacher has said that I need to have real life, practical applications of the model, and to also have a variable I can change and talk about. So, I've decided to change for now, looking more at magnets themselves. We have neodymium magnets and I was winding if calculating the force needed to separate the magnets decrease over distance and maybe plot a relationship. Do you have any advice?
