Homework Help: Help! Science Fair 1 Week Away

  1. Jan 21, 2010 #1
    1. The problem statement, all variables and given/known data

    The Science fair is only a week away, and i haven't really started my project. It is which factor affects the strength of an electromagnet the most. The factors I am using so far are number of coils, diameter of core, thickness of wire, and voltage of power source.
    I want to do well in the science fair, and I just need advice from you guys about how I can make this project stand out.

    2. Relevant equationsnone

    3. The attempt at a solution

    I just need suggestions as to what you guys would do if you were in my shoes.

    I can only speak for myself and not for the other "guys." If I were in your shoes, I would read about electromagnets on the web and perhaps buy or borrow a physics book that I can understand and that describes the working principles of electromagnets. Once I understand the basic principles, I would go to the hardware store and buy whatever supplies I need to make one and see what it does and how. I would also start all this much sooner than a week before the project is due.
