1. The problem statement, all variables and given/known data I need to get 2 major loops in my method or hypthesis. My experiment is which of the following factors affects strength of electromagnet the most: number of coils, the voltage of the power source, the diameter of the core, or the thickness of the wire. Can you guys give me loops that I can do with each of these factors. I'm in high school. 2. Relevant equations None 3. The attempt at a solution I really don't know. The loops is the only spot I'm stuck on.
