Hallo everyone! I'd like to build a simple generator for a project. Like this picture here: http://www.interactives.co.uk/images/DSCN7717crr.JPG [Broken] I have everything I need but one think keeps coming into mind... Mechanical resistance?(Not friction due to material's touching each other like the conventional generator.) I'm building a generator exactly the same as the one in the image. The mechanical resistance I'm worried about is when I'm actually adding a "load" to the generator can I feel a mechanical resistance? Do I have to add more mechanical energy from my hand? If I'm applying simple mechanical energy from my hand when adding a load to the coils like a set of led's would I feel a mechanical difference by having a load or not? Hope I'm making sense... All in all I'm asking about Mechanical resistance if there is a load" light bulb's or small motor" attached to it. Thank you!
