I am currently in the planning stages of creating a small homemade generator, or at least the magnet/coils part of one. not sure yet what the mechanism will be to cause it to spin (wind? water? heat?)
anyway, my general idea is to have two rotating plates of magnets with a stationary plate of coils in between. i.e. magnets of alternating polarity arranged around the circumference of two discs. coils sandwiched in between. the magnets rotate, the alternating polarity of the magnet arrangement induces current... and so on to some 3-phase power generation.
this is not meant to be a huge generator, more of an experiment really, but i was wondering if anyone knew where to find the strengths of various-sized neodymium magnets, so I can figure out which ones to use to give me the kind of output to price ratio that I want. I also need to figure out what gauge of wire to use for the coils, but that depends on the magnet strength of course, so that can come later.
thanks in advance
