1. The problem statement, all variables and given/known data I'm in high school and I haven't taken physics yet, but I'm doing a science project where I'm comparing a space shuttle liftoff to a liftoff using a magnetic field created by coils. I found the force that the space shuttle uses at liftoff and now I have to scale it down. When I scale it down, how can I convert it to Henrys so I can use the right amount of power. Am I thinking in the right direction? I'm sorry if this is a newbie question, its just I don't have much guidance.
