AC Generator Help!

  1. Feb 7, 2004 #1
    Hey, I need to make an AC Generator for a school physics assignment.
    It will be marked on how much voltage it generates.

    I will be doing this using induction with the following equipment:
    * Permanent magnet
    * Coil/Wire
    * Iron Core
    * Split Rings/Brushes ?

    My questions are:
    * What's the best material for the coil/wire?
    * How can I make a good iron-core?
    * When constructing the coil, does it matter if the coil is wounded so that it is touching itself throughout the iron-core (ie. there is no visible spacing between the coils/turns)?
    * Are split rings/brushes necessary? What are they for?

    Any help is appreciated.
