I want to make a dynamo for fun. But I have some questions about the working principle.Image HereIn the image, the system prepared with rectangle magnet. But i have circle magnet and actually it's seems that it is not so much powerful. Does it change anything?I planing to make more copper winding and cover the iron with it. If i do this, can i get more electrical energy?The system in the picture can actually work? I'm worry about that bulb, it feels like the system can't produce enough electrical energy. Will it work or should i try something else?Thanks for the answers. via /r/DIY http://ift.tt/2lwHFtj
