I just saw a demonstration of an induction motors and was wondering if its possible to build an AC or DC generator without contact brushes? The only way I can think of is if you have a permanant magnet spinning near or within a coil or wire. Is there anyway to produce a magetic field with just kinetic motion? I've searched the net and haven't found any explanation. If you have a link please include it.
