I added the definitions into the text of the post above. Thanks! lac,

So, I am not sure how to make a calculator for that. For a generator or dynamo, it is not really just the length of the wire that is important. The induced voltage follows Faraday’s Law. From [1], Faraday's Law states that the induced electromotive force in a closed loop of wire (i.e. voltage) is directly proportional to the time rate of change of magnetic flux through the loop.

Correct me if I' m wrong. If my logic is correct, Reference thickness, you’re refering to the thickness spec on the ink supplier’s data sheet. Correct me if I’ m wrong.

I’ll put it on my “to do” list. For reference, the density I found for copper is 8.96 g/cm^3. [Update 2/29/08: I added the mass calculation to the calculator. Brad] Hi Rob,

I use it probably once/week on average! One thing I'm looking for right now and missing is the ability to calculate the mass of copper given the inputs. It should be difficult since you've got diameter and length. I could look up density (which is what I will do). Of course, it would just be an estimate (issues such as insulation mass and stranded vs. un-stranded) but would be useful. Thanks again! Hey Brad, thank you so much for this calculator.
