    i need to build the generator shown in this link
    The magnets shown in that pages are not available here in my area.
    I want replace them with electro magnet. I'll look after the brush arrangement. Can anybody suggests me about the electro magnets. I need the similar magnetic strength. I'll give the DC voltage from a rectifier through the brushes. How many turns and which gauge i have to use? There is no alternative for earth magnets here.
    It is easy or tough, i need to design the artificial magnets.
    please help me.
