I am building a AC generator - 12 magnets (2" dia - 1" thick) and 9 coils - face of the core is also 2" dia. the core is mild steel. when the mags pass over the steel cores eith NO COPPER WIRE wound on it the steel gets very, very HOT (changes color). Is this normal ? is there a way to stop this heat build-up. would facing all the mags with North or south all on one side of the rotor help? are the mags TOO Close to each other - should there be more space between them.since the mags are 2" dia should there be a 2" space between them . we are only testing with ONE core at this time and this one gets very hot.
can anyone with more knowledge help?
thanks,
Jim
