Desperate for help!!!!!!!!!!!!!!!! 1. The problem statement, all variables and given/known data I am doing an electromagnet project. I am a bit lazy and was asking if you guys could give me a list of ALL the materials I need to compete in the science fair. I'm in 10th grade, and my question is which factor affects strength of electromagnet the most. Things like # of coils or thickness of wire. I would be extremely happy if you guys would help. 2. Relevant equations none 3. The attempt at a solution I am having major stress in my life, and I just need someone to give me a list so I can go to the store and buy those materials.
