Selection of material for wind generator

  1. Jun 10, 2007 #1
    sir i am tying to make a wind electricity generator, but i am confused about selection of material that i have to use for the project.
    can hysterisis loop help me? how? what the graph will show to me?
    please explain. the use of steal magnet will make my generator light and more efficient or copper will make it so?:rolleyes:

    I'm a bit confused by the question. Do you mean that you're actually building the generator itself rather than just incorporating a pre-made one into your design?
    Anyhow, there's no such thing as a copper magnet, so that part of the question doesn't really apply. You could use rare-earth magnets for better efficiency, but I don't expect that the return would be worth the expense.
