I need to make a generator. The really small ones that can light up a very tiny lightbulb. Basically, I need horse shoe magnets, I know that bit, bet im having trouble how to create the coil and wrap the magents, and how to build it. How do I make a coil? I don't want to buy one I want to make one. Can someone explain??

You have to buy wire. I suggest fine magnet wire available at RAdio Shack. Wind it around your finger tips :(two or three fingers) to make the coil.

I suggest start with a motor first. Making a generator is far more difficult.

at which temperature is the oil most viscous?
