Loops for Project

  1. Dec 4, 2009 #1
    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

    3. The attempt at a solution
    I really don't know. The loops is the only spot I'm stuck on.

    What do you mean by loops? Flaws?

    I mean a feedback loop. The feedback loop is in the need to go back to the "Asking a Question" stage should the experiment stage not support the answer stage (Hypothesis).

    I believe that the number of coils will affect its strength the most. I haven't had anything go wrong yet so I would llike to know what feedback loops might I try because I need 2.
